'''''Inferno''''' is the fourth and final serial of the [[Doctor Who (season 7)|seventh season]] of the British [[science fiction television]] series ''[[Doctor Who]]'', which was first broadcast in seven weekly parts on [[BBC One|BBC1]] from 9 May to 20 June 1970. The serial remains the last time a ''Doctor Who'' story was transmitted in seven episodes. This serial was also the last regular appearance of [[Caroline John]] in the role of [[Liz Shaw]].

In the serial, the alien [[Time travel in fiction|time traveller]] the [[Third Doctor]] ([[Jon Pertwee]]) transports himself "sideways in time" to a [[Parallel universes in fiction|parallel world]], where a British drilling project causes catastrophic amounts of heat and force to be unleashed when it penetrates the [[Earth]]'s crust.

==Plot==
The [[Third Doctor]] and [[UNIT]] are called in to investigate a murder at Project Inferno, an effort to drill through the Earth's crust to harness great energies within the planet's core. It transpires that the drilling is producing a green ooze that transforms all who touch it into savage humanoid creatures called Primords, who can only be killed via extreme cold. Unbeknownst to anyone, the project leader, Professor Stahlman has been infected and is in the early stages of the change. After quarrelling with Stahlman, the Doctor attempts an experiment on the detached TARDIS console, but a freak accident transports him into a parallel space-time continuum.

In this [[Parallel universes in fiction|new universe]], where [[Great Britain]] is a [[British fascism|fascist republic]], the Doctor is captured and interrogated by [[Brigadier Lethbridge-Stewart]]'s counterpart, a sadistic, eyepatch-wearing military commandant known as the Brigade Leader, along with the counterpart of the Doctor's companion [[Liz Shaw|Liz]], who in this universe became a military officer instead of a scientist. When the drill penetrates the Earth's crust it unleashes immense amounts of seismic forces, heat, and poisonous gases, along with more of the ooze, which Stahlman's counterpart, now mutated, uses to transform most of the remaining project staff into more Primords. The Doctor determines that the unleashed energies of the core will eventually disintegrate the planet and is able to persuade the surviving staff members to help him return to his own universe and prevent a similar catastrophe. They eventually succeed in restoring power to the TARDIS console despite repeated Primord attacks, but Liz's counterpart is forced to kill the Brigade Leader when he turns on the Doctor, who narrowly escapes as the Project Inferno facility, and Britain itself, is destroyed by a massive volcanic eruption.

Back in his own reality, the Doctor urgently tries to have the drilling stopped, but like in the other reality his warnings are ignored. This time, however, the slower pace of the drilling means that Stahlman fully transforms into a Primord before the crust is penetrated instead of afterwards, and after the Doctor kills him with a [[fire extinguisher]], the drilling is stopped in time to prevent disaster, saving the human race as a result. Satisfied that the TARDIS console is now working again, the Doctor attempts to depart, only to end up landing in a local rubbish dump.

==Production==

Scriptwriter Don Houghton was a personal friend of the ''Doctor Who'' script editor, Terrance Dicks: they had worked together for Lew Grade at ATV in the 1960s, on the TV soap opera ''Crossroads''. During a train journey, Houghton discussed with Dicks his idea for a serial based on the real life drilling project known as [[Project Mohole]]. Budgetary limitations eventually led to the concept of the parallel world, so that the same actors and sets could be used for seven episodes, rather than the four episodes in Houghton's original story breakdown, in order to cut costs.<ref>{{cite episode |series=Barry Letts – Who & Me |url=https://www.bbc.co.uk/programmes/b00rv45s |network=BBC Radio 7 |title=Episode 7 |airdate=18 April 2010}}</ref>

Despite [[Douglas Camfield]] receiving sole credit as director, the studio scenes for episodes 5 to 7 were directed by producer [[Barry Letts]]<ref>https://www.amazon.co.uk/Directed-Douglas-Camfield-Michael-Seely-ebook/dp/B09GW7K31N/ref=tmm_kin_swatch_0</ref> after Camfield had a minor heart attack on April 27, 1970. Letts later stated that Camfield's preparations were so meticulous, he merely followed Camfield's plans for Episodes 5 and 6, but the last episode was largely his own work. Camfield remained credited as director, as BBC regulations at the time forbade Letts from being credited for more than one production role (i.e. as both producer and as director), but, more importantly, Letts did not want Camfield's illness to become widely known lest it harm his career.

Stuntman Derek Ware did not actually perform the stunt in which his character, the mutated RSF Trooper Wyatt, having been shot, falls to his death from the top of one of the chemical tanks, in case he was injured (since he was also needed for the subsequent studio recording). His place was taken by Roy Scammell, who (ironically) also played the soldier who fired the fatal shot. Ware stated in an interview that Scammell had already signed the contract to do the fall before Ware had been cast as Wyatt. At the time it was filmed, it was the highest fall ever performed by a British stuntman.

John Levene's portrayal of Benton as a Primord was inspired by Shakespeare's play ''[[Richard III (play)|Richard III]]'' (because of the Primord creature's hump).<ref>{{cite video

Caroline John said she enjoyed her role as Section Leader Elizabeth Shaw, as it was fun playing Liz as a "baddie". She also said she hated doing the scenes in which she was playing her usual role, because it was boring compared to playing the parallel character. She was upset, though, about the scene in which Section-Leader Shaw shot Brigade Leader Lethbridge-Stewart, as she was pregnant at the time. As a result, the scene was recorded with the weapon fired from out-of-shot, after which Shaw was shown returning the gun to her holster.<ref>Pixley, Andrew, "DWM Archive: Inferno", ''[[Doctor Who Magazine]]'', #305, 27 June 2001, [[Panini Comics]], p. 41.</ref> Though her pregnancy has sometimes been cited as the reason John left the show, producer Barry Letts had already made the decision not to renew her contract before learning of it.<ref>{{cite book |last1=Howe |first1=David J. |last2=Walker |first2=Stephen James |title=The Television Companion: The Unofficial and Unauthorised Guide to Doctor Who |date=2003 |publisher=Telos |isbn=9781903889510 |page=267 |url=https://books.google.com/books?id=V075SAAACAAJ |access-date=24 July 2025 |ref=Howe & Walker}}</ref>

During the scenes set on the parallel Earth, images of the British Republic's leader are seen on posters. The image used is that of BBC visual effects designer Jack Kine,<ref name="ReferenceA">{{Cite web|url=https://www.bbc.co.uk/programmes/articles/1tQ6CjDLDTVmqQmmLKw0NSh/the-fourth-dimension|title = BBC One - Doctor Who, Season 7, Inferno - the Fourth Dimension}}</ref> in homage to the 1954 BBC adaptation of Orwell's novel ''[[Nineteen Eighty-Four (UK TV programme)|Nineteen Eighty-Four]]'' in which the face of [[Big Brother (1984)|Big Brother]] was actually that of the BBC's head of television design [[Roy Oxley]] (Kine had worked on the visual effects for that production).

Episode 6 has a small damaged section on the American NTSC videotape which was used as the source of the colour signal for the restoration, which the [[Doctor Who Restoration Team]] replaced by recolouring the appropriate section of the b/w film recording.<ref>{{cite web |url=http://www.purpleville.pwp.blueyonder.co.uk/rtwebsite/inferno-prelim.htm |title=Doctor Who Restoration Team – Inferno notes |url-status=dead |archive-url=https://web.archive.org/web/20060627215835/http://www.purpleville.pwp.blueyonder.co.uk/rtwebsite/inferno-prelim.htm |archive-date=2006-06-27 }}</ref>

===Locations===
The exterior shots used in this production were filmed at Kingsnorth Industrial Estate on the [[Hoo peninsula]], [[Kent]] which featured as the setting for the Inferno project.<ref>{{cite web|author=Kent Film Office|url=http://kentfilmoffice.co.uk/1970/05/doctor-who-inferno-1970/|title=Kent Film Office Doctor Who – Inferno Article |date=9 May 1970 }}</ref>

===Music===
Director [[Douglas Camfield]] chose not to commission any new incidental music for the serial, but instead made use of existing library recordings by members of the [[BBC Radiophonic Workshop]]. These included: "Blue Veils & Golden Sands"<ref>{{cite web |last1=Szpirglas |first1=Jeff |title=Top 10 classic Doctor Who scores |url=https://www.denofgeek.com/tv/top-10-classic-doctor-who-scores/ |website=www.denofgeek.com |date=28 June 2010 |access-date=30 September 2021}}</ref> and "The Delian Mode" (both by [[Delia Derbyshire]]); "Battle Theme", "Homeric Theme", "Attack of the Alien Minds" and "Souls in Space" (all by [[Brian Hodgson]]); and "Build Up To" (by [[David Vorhaus]]). In addition, as was usual, Brian Hodgson supplied new sound effects for the serial, including ''"[[TARDIS#Controls|Tardis Control]] On & Warp Transfer"''.<ref name="DiscogsBBCRWv2">{{cite web|url=http://discogs.com/BBC-Radiophonic-Workshop-Doctor-Who-At-The-BBC-Radiophonic-Workshop-Volume-2-New-Beginnings-1970-198/release/886728|title=Doctor Who At The BBC Radiophonic Workshop – Volume 2: New Beginnings 1970–1980 (CD) at Discogs|publisher=[[Discogs]]|access-date=12 Feb 2011}}</ref>

According to the DVD release notes from the ITV serial ''[[Timeslip]]'', this music subsequently featured in the second episode of that show's serial ''The Time Of The Ice Box''.

===Cast notes===
Camfield cast [[John Levene]] as the scripted UNIT sergeant, allowing the character to become that of Benton, who Camfield had cast Levene as in ''[[The Invasion (Doctor Who)|The Invasion]]'' (1969). As a result of this decision, Benton was also included in the previous serial, ''[[The Ambassadors of Death]]''.<ref>{{cite AV media notes |last1=Pete |first1=McTighe |author-link1=Pete McTighe |date=2025 |chapter=Inferno |title=''Doctor Who'': The Collection Season 7 |publisher=[[BBC Studios]] |page=22}}</ref>

Christopher Benjamin, who plays Sir Keith Gold, subsequently appeared as [[Henry Gordon Jago]] in ''[[The Talons of Weng-Chiang]]'' (1977),<ref>{{Cite web|url=https://www.bbc.co.uk/doctorwho/classic/episodeguide/talonswengchiang/detail.shtml|title=BBC - Doctor Who Classic Episode Guide - The Talons of Weng Chiang - Details|website=www.bbc.co.uk}}</ref> and as Colonel Hugh Curbishley in "[[The Unicorn and the Wasp]]" (2008). He also played Tardelli in the audio play ''[[Grand Theft Cosmos]]''. Most recently, he has returned to play the character of Henry Gordon Jago in a long-running series of audio dramas titled ''Jago & Litefoot'' based upon the situation established in ''[[The Talons of Weng-Chiang]]''.

The role of Petra Williams was given to Sheila Dunn when [[Kate O'Mara]] was unavailable to play the part.<ref name="ReferenceA"/> O'Mara would, years later, be cast as [[The Rani]], a renegade Time Lord. Dunn was the wife of this story's co-director, Douglas Camfield, and had appeared twice before in ''Doctor Who'', in ''[[The Invasion (Doctor Who)|The Invasion]]'' (1968) and ''[[The Daleks' Master Plan]]'' (1965–66).

Ian Fairbairn (Bromley) had previously appeared as Questa in ''[[The Macra Terror]]'' (1967) and as Gregory in ''[[The Invasion (Doctor Who)|The Invasion]]'', and would subsequently feature as Doctor Chester in ''[[The Seeds of Doom]]'' (1976).<ref>{{Cite web|url=https://www.bbc.co.uk/doctorwho/classic/episodeguide/seedsofdoom/detail.shtml|title=BBC - Doctor Who Classic Episode Guide - The Seeds of Doom - Details|website=www.bbc.co.uk}}</ref>

In 2009, Mark Braxton of ''[[Radio Times]]'' awarded the serial five stars out of five and praised the intense atmosphere, with a "good, scary, cautionary" plot. However, he noted that the Primords were not the best physical design and their relationship to the events was not cleared up.<ref name="Radio Times">{{cite web|first=Mark|last=Braxton|url=http://www.radiotimes.com/news/2009-10-07/inferno|title=Doctor Who: Inferno|work=[[Radio Times]]|date=7 October 2009|access-date=24 February 2013}}</ref> Reviewing the special edition DVD release, Dave Golder of ''[[SFX (magazine)|SFX]]'' gave the serial four out of five stars.

===Home media===
The original 625-line [[PAL]] videotapes were wiped for reuse in the mid 1970s. [[BBC Enterprises]] retained the black-and-white film recordings made for overseas sales. In 1985, a set of broadcast quality 525-line [[NTSC]] videotapes were returned from Canada. Due to the complexities of conversion, the original re-conversions back to 625-line PAL left the picture looking a little blurred and faded when the story was released on [[VHS]] in the UK in May 1994. Prior to this, episode 7 of the story had been included on the 1992 VHS release, ''The Pertwee Years'' (along with the final episodes of both ''[[The Dæmons]]'' and ''[[Frontier in Space]]'').  When ''Inferno'' was released on Region 2 [[DVD]] on 19 June 2006, however, the picture quality had been markedly enhanced through the use of the "[[Reverse Standards Conversion]]" procedure. This serial was also released as part of the [[Doctor Who DVD Files]] in Issue 44 on 8 September 2010.

A special-edition re-release of the story was released on 27 May 2013.<ref>{{cite web|url=http://www.doctorwhonews.net/2012/05/dwn230512212008-dvd-update-ambassadors.html |title=DVD Update: The Ambassadors of Death / Special Editions |publisher=Doctor Who News |access-date=2013-10-09}}</ref> This uses the same technique employed on the special-edition DVD of ''[[The Claws of Axos]]'': the colour information from the Reverse Standards Conversion video was combined with luminance information from a geometrically-corrected remaster of the b/w 16mm-film recording, with [[VidFIRE]] applied to the studio interior scenes to recreate the 50-field interlaced look.<ref>{{Cite web|url=http://www.impossiblethings.net/restorationteam/InfernoSE.htm|title=Inferno - SE|website=www.impossiblethings.net|access-date=7 June 2019|archive-date=7 June 2019|archive-url=https://web.archive.org/web/20190607062528/http://www.impossiblethings.net/restorationteam/InfernoSE.htm|url-status=dead}}</ref> The resulting picture is sharper than the RSC version.<ref>{{cite web |url=http://www.tellytechblog.com/2013/05/doctor-who-inferno-special-edition-dvd.html |title=PAGE Telly TechL Doctor Who: Inferno – Special Edition – DVD Review |url-status=dead |archive-url=https://web.archive.org/web/20141222054513/http://www.tellytechblog.com/2013/05/doctor-who-inferno-special-edition-dvd.html |archive-date=2014-12-22 }}</ref>

The Canadian videotapes include an additional scene in Episode 5 that was not originally transmitted in the UK, but was retained for overseas screening (and has also appeared on both the [[Gold (UK TV channel)|UK Gold]] transmissions and BBC Video's VHS release).<ref>{{Cite web|url=http://www.impossiblethings.net/restorationteam/inferno-prelim.htm|title=Inferno|website=www.impossiblethings.net|access-date=7 June 2019|archive-date=7 June 2019|archive-url=https://web.archive.org/web/20190607062527/http://www.impossiblethings.net/restorationteam/inferno-prelim.htm|url-status=dead}}</ref> Set in the Brigade Leader's office with the Doctor, the Brigade Leader and Section Leader Shaw listening to a BBC radio news report voiced by Jon Pertwee, who imitates the style of [[William Joyce]], the scene was cut before transmission because Pertwee's voice was too identifiable. The radio announcer names the area where the Inferno project is taking place as Eastchester; the name is not mentioned anywhere else in the story, but is subsequently mentioned in spin-off media. The scene was included as an extra on the DVD releases, with the episode itself presented exactly as originally transmitted (using the b/w film recording for reference when editing).<ref>{{Cite web|title=Inferno|url=http://impossiblethings.net/restorationteam/inferno-prelim.htm|access-date=2021-09-13|website=impossiblethings.net}}</ref>
