This truly is a tragic loss. Anton Yelchin was only twenty-seven when he was killed, seemingly as the result of a dreadful accident. Yelchin was best known for his role as Chekov in the new iteration of Star Trek, and his sudden death is going to put a very different complexion on the experience of watching Star Trek Beyond. Yelchin was a fine young actor, although it's clear we had yet to see the best from him. He was the best thing in Terminator Salvation and the Fright Night remake. The bulk of his work I have yet to see, but one thing that I can vouch for is Odd Thomas, a hugely underrated supernatural adventure in which he plays the title role. He'd already been cast in further roles that he will now never play.
Yelchin's personal life makes for some interesting reading itself. Born in Leningrad to a Jewish family, he was raised by people who had experienced a great deal of persecution under the Soviet regime. His family fled the USSR when he was only six months old, having received refugee status. His family were sportspeople and artists, so it's not surprising that he went into the performing arts, beginning acting at the age of nine, beginning a rich career that also involved time in a punk band. He could have gone on to do great things.
