American actor who played Pavel Chekov in the three Kelvin Timeline films and died weeks before Star Trek Beyond was released.
Anton Yelchin (1989–2016) was an American actor born in the Soviet Union who began his career as a child actor. His films included Hearts in Atlantis, Alpha Dog, Terminator Salvation, in which he played Kyle Reese, Like Crazy and Green Room.
Yelchin played the young navigator Pavel Chekov in Star Trek (2009), Star Trek Into Darkness (2013) and Star Trek Beyond (2016), with a thick accent and eager manner. He died in June 2016, about a month before Beyond opened; the film was dedicated to him and to Leonard Nimoy, and the role was not recast.
