The Oscar winner was perhaps best-known for playing Captain Von Trapp in The Sound of Music, but he famously starred as Klingon General Chang in the 1991 film Star Trek 6: The Undiscovered Country. Plummer reprised the role of Chang for the 2000 video game Star Trek: Klingon Academy, which explained how his character lost an eye. The video below shows the intro to the game: Players are currently gathering at the various memorials located within Star Trek Online (the game’s memorial plaques pay tribute to the cast and crew of the Star Trek series and films). Redditor Lars2510 took to the Star Trek Online sub to post a screenshot of a gathering at the Klingon homeworld Qo’noS: Here’s a screenshot from redditor ReeseKaine, posted to Imgur, of another gathering at Qo’noS: Twitter user Grumpy Old Nord posted screenshots of a gathering at the memorial on Deep Space Nine: Players are also creating characters in Chang’s image: The official Star Trek Online Twitter page also paid tribute to the late Plummer: Tributes poured in from the world of Star Trek following Plummer’s death. George Takei, who played Hikaru Sulu in the original series and movies, called the actor a “giant of stage and screen”. And William Shatner, who played Captain Kirk in the original series, said “I am so sad to lose him”.
