'''Walter Marvin Koenig''' ({{IPAc-en|ˈ|k|eɪ|n|ɪ|ɡ}}; born September 14, 1936) is an American actor and screenwriter. He began acting professionally in the mid-1960s and quickly rose to prominence for his supporting role as Ensign [[Pavel Chekov]] in ''[[Star Trek: The Original Series]]'' (1967–1969). He went on to reprise this role in all six original-cast ''Star Trek'' films, and later voiced President Anton Chekov in ''[[Star Trek: Picard]]'' (2023). He has also acted in several other series and films including ''[[Goodbye, Raggedy Ann]]'' (1971), ''[[The Questor Tapes]]'' (1974), and ''[[Babylon 5]]'' (1993). In addition to his acting career, Koenig has made a career in writing as well and is known for working on ''[[Land of the Lost (1974 TV series)|Land of the Lost]]'' (1974),'' [[Family (1976 TV series)|Family]]'' (1976), ''[[What Really Happened to the Class of '65? (TV series)|What Really Happened to the Class of '65?]]'' (1977) and ''[[The Powers of Matthew Star]]'' (1982).

==Career==

===Early work===
In [[Gene Roddenberry]]'s first television production, the 1963–64 NBC series ''[[The Lieutenant]]'', Koenig played a significant role as noncom Sgt. John Delwyn, who is recommended for [[Officer Candidates School (United States Marine Corps)|Officer Candidates School]] by the series protagonist, Lt William T. (Tiberius) Rice, played by [[Gary Lockwood]]; (in episode 27, "Mother Enemy", aired on April 4, 1964). The plot twist, at the height of the US–Soviet [[Cold War]], is that Sgt Delwyn's visiting mother is a prominent, and politically active, American Communist Party member. This sets up various interesting plot tensions involving Delwyn, Rice, and Rice's CO, Capt. Rambridge, played by [[Robert Vaughn]].{{citation needed|date=July 2018}}
In 1964, Koenig portrayed a New York City juvenile gang leader in an adaptation of ''[[Memos from Purgatory]]'' for ''[[The Alfred Hitchcock Hour]]''.

{{quote box|align=right|width=33%|quote = I was one of only two people who auditioned for the part, which is quite extraordinary. Considering that this has so materially affected the last 35 years of my life&nbsp;... a couple of hours after I auditioned I heard that I had gotten the role.{{r|bbckoenig}}}}

Koenig began playing Ensign Pavel Chekov, navigator on the [[USS Enterprise (NCC-1701)|USS ''Enterprise'']], in the original ''Star Trek'' television series in the second season, and continued in the role in all of the films featuring the original cast, including ''[[Star Trek Generations]]''.

Koenig was unfamiliar with science fiction before being cast on ''Star Trek''.<ref name="tomorrow19760204">{{Cite AV media |url=http://www.tvparty.com/70-star-trek.html |title=Star Trek cast on Tom Snyder's Tomorrow, 1976 |type=Television production |orig-date=1976-02-04 |series=Tomorrow |access-date=2024-03-15 |via=YouTube}}</ref> One of only two actors to audition, he was cast as Chekov almost immediately primarily because of his resemblance to British actor and singer [[Davy Jones (musician)|Davy Jones]] of [[the Monkees]]. Show creator Gene Roddenberry hoped that Koenig would increase the show's appeal to young people. The studio's publicity department, however, falsely ascribed the inclusion of Chekov to an article in ''[[Pravda]]'' that complained about the lack of Russians in ''Star Trek''.<ref name="bbckoenig">{{Cite web|url=https://www.bbc.co.uk/cult/st/interviews/koenig/printpage.html|title=Walter Koenig – Chekov in the Original Star Trek|publisher=BBC|archive-url=https://web.archive.org/web/20011115182318/http://www.bbc.co.uk/cult/st/interviews/koenig/printpage.html|archive-date=November 15, 2001|access-date=May 7, 2011|url-status=dead}}</ref>{{Failed verification|date=May 2025}}

As the 30-year-old's hair was already receding, costume designers fashioned a Davy Jones-style "moptop" hairpiece for him. In later episodes, his own hair grew out enough to accomplish the look with a comb-over.<ref>Vejvoda, Jim and Phil Pirrello. "Star Trek: The Original Series – Season 2 Review." IGN.com, September 18, 2009.</ref>

Roddenberry asked him to "ham up" his Russian accent to add a note of comic relief to the series. Chekov's accent has been criticized as inauthentic, in particular Koenig's substituting the "w" sound in place of a "v" sound (e.g., "wodka" for "vodka" or most famously "wessel" for "vessel"); Koenig has said the accent was inspired by his father, who had the same difficulty with the "v" sound.<ref name=cbc/>

Most of Koenig's [[fan mail]] came from children, and his popularity with fans contributed to him soon receiving a contract as a regular ''Star Trek'' cast member; this surprised Koenig, who had initially been told that Chekov would only be a recurring role.{{r|bbckoenig}}<ref name="davis20130907">{{cite web | url=http://io9.com/gene-roddenberrys-1968-memo-on-improving-star-treks-c-1267131265| title=Gene Roddenberry's 1968 memo on improving Star Trek's characters|work=io9|date=September 7, 2013|access-date=September 7, 2013|author=Davis, Lauren}}</ref> When the early episodes for season two of ''Star Trek'' were filmed, [[George Takei]] was absent while completing the movie ''[[The Green Berets (film)|The Green Berets]]'', so Chekov was joined at the ''Enterprise'' helm by different characters. When Takei returned, the two actors had to share a dressing room and a single script per episode. This reportedly angered Takei to the point where he considered leaving the show, although Koenig observed in a 2016 interview that, while sharing a dressing room with Takei and [[James Doohan]], the three finally recognised their status as supporting players and after that "didn't think twice about it".<ref>{{Cite web|url=https://www.tvinsider.com/96257/star-treks-walter-koenig-on-chekovs-haircut-and-other-decades-old-rumors|title = 'Star Trek's Walter Koenig on Chekov's Haircut and Other Decades-Old Rumors| date=September 6, 2016 }}</ref> Koenig and Takei have since become good friends, to the point that Koenig served as best man at Takei's wedding in 2008.<ref>Michael Weinfeld (June 5, 2008). "George Takei and partner plan to wed in September". ''USA Today''. Associated Press. Retrieved 2008-10-24.</ref>

The character of Chekov did not appear in the animated ''Star Trek'' series. The show's producers had declined to hire Koenig for budgetary reasons and the actor wasn't even aware that he would not be included in the cast until a fan informed him at a [[Science fiction convention|''Star Trek'' convention]]. Although Roddenberry would hire Koenig as a writer and purchased his script for an episode of the show titled "[[The Infinite Vulcan]]", Koenig later confessed that he was upset at being left out of the cast of the animated series.<ref>{{cite journal|last=Mangels|first=Andy|date=Summer 2018|title=Star Trek: The Animated Series|journal=RetroFan |issue=1|page=28|publisher=[[TwoMorrows Publishing]]}}</ref> "The Infinite Vulcan" makes him the first cast member to write a ''Star Trek'' story for television.

Koenig received [[Saturn Award]] nominations for [[Saturn Award for Best Supporting Actor|Best Supporting Actor in a Film]] for both ''[[Star Trek II: The Wrath of Khan]]'' and ''[[Star Trek IV: The Voyage Home]]''. Koenig reprised the role of Chekov for the fan webseries ''[[Star Trek: New Voyages]]'', "To Serve All My Days", and the independent Sky Conway/[[Tim Russ]] film, ''[[Star Trek: Of Gods and Men]]'', both in 2006, and ''[[Star Trek: Renegades]]'' in 2015. According to the teaser for ''Renegades'' episodes 2 and 3, this would be the last time Koenig played the role of Chekov.

In the last episode of the third season of ''[[Star Trek: Picard]]'', aired in 2023, Koenig voiced an audio transmission from Federation President Anton Chekov, implied to be Pavel's son; the name references [[Anton Yelchin]], who played Chekov in the [[J. J. Abrams]]-directed ''Star Trek'' films.<ref>{{Cite web|url=https://www.giantfreakinrobot.com/ent/star-trek-picard-walter-koenig-chekov.html|title=Star Trek Original Series Actor Returns To The Franchise|first=Michileen|last=Martin|date=April 20, 2023|website=GIANT FREAKIN ROBOT|accessdate=May 20, 2023}}</ref>

[[Typecast]] as Chekov, Koenig found a great disparity between the adulation from [[Trekkie]]s at [[science fiction convention|''Star Trek'' convention]]s and his obscurity in Hollywood,{{r|tomorrow19760204}} stating that "people are interested in Chekov, not me".<ref name="michaels19781210">{{Cite news |last=Michaels |first=Marguerite |date=December 10, 1978|title=A Visit to Star Trek's Movie Launch |pages=4–7|work=[[Parade (magazine)|Parade]]|url=https://trekkerscrapbook.com/2013/04/23/the-daily-scrapbook-parade-magazine-cover-december-10-1978/ |access-date=June 1, 2022}}</ref> Before the ''Trek'' movies started, Koenig found some work as a writer. He submitted freelance scripts to a number of shows, and was the main writer on the show ''[[What Really Happened to the Class of '65?

After Chekov, Koenig had a recurring role as [[Psi Corps|Psi Cop]] [[Alfred Bester (Babylon 5)|Alfred Bester]] on the television series ''[[Babylon 5]]''. He was a "Special Guest Star" in twelve episodes and, at the end of the third season, the production company applied for an [[Emmy Award|Emmy]] nomination on his behalf. He was slated to play Bester on the spin-off series ''[[Crusade (TV series)|Crusade]]'', but the series was cancelled before his episode was filmed. The character name of "Alfred Bester" was an homage to [[Alfred Bester|the science-fiction writer of the same name]].<ref>{{Cite web |title=Guide Page: "Ship of Tears" |url=http://www.midwinter.com/lurk/guide/058.html#JS |access-date=2022-03-11 |website=www.midwinter.com}}</ref>

Koenig played "Oro" in two episodes of the Canadian science fiction television series ''[[The Starlost]]'', which aired in 1973 on Canada's [[CTV Television Network|CTV television network]]. He filmed a few [[Full-motion video|FMV]] sequences for a re-released copy of the game ''Star Trek Starfleet Academy'' for PCs.{{citation needed|date=July 2018}} The game was later cancelled, but considerable footage from it was recycled for the film ''[[Game Over (2003 film)|Game Over]]'', with Koenig's dialogue dubbed over in order to retrofit his performance into the role of a computer [[hard drive]].{{citation needed|date=July 2018}}

Koenig's film, stage, and TV roles span fifty years. He has played roles ranging from a teenage gang leader (''[[Alfred Hitchcock Presents]]'') to Scandinavian fiancé Gunnar in the ''[[Gidget (TV series)|Gidget]]'' episode entitled "Gidget's Foreign Policy", to a Las Vegas entertainer (''[[I Spy (1965 TV series)|I Spy]]''). He returned to space with a starring role in ''[[Moontrap]]'' and played a futuristic dictator in the video game ''[[Maximum Surge]]''.<ref>{{cite magazine|title=Maximum Surge Packs Plenty of Star Power|magazine=[[Electronic Gaming Monthly]]|issue=75|publisher=[[Ziff Davis]]|date=October 1995|page=27}}</ref>

During the early 1990s, he starred in a touring production of the play ''The Boys in Autumn'', playing a middle aged [[Tom Sawyer]], who reunites with childhood friend [[Huckleberry Finn]]. Fellow ''Trek'' actor [[Mark Lenard]] played Finn.<ref>{{Cite news | url=https://www.latimes.com/archives/la-xpm-1990-08-04-ca-829-story.html | title=The Twain Meet Again in 'Boys in Autumn' | work=Los Angeles Times | date=August 4, 1990 |author=Loynd, Ray }}</ref>
