The curse of the '27 Club' strikes again after Star Trek actor Anton Yelchin dies
It's called the 27 Club and the term was created in the 1970s after four famous musicians, all aged 27, died within two years of each other.
Brian Jones from the Rolling Stones, Jimi Hendrix, Janis Joplin and The Doors' Jim Morrison all passed away between 1969 and 1971.
It's mainly been used for musicians over the years but has included actors and other stars as well.
And now the list tragically has another name, Star Trek's Anton Yelchin.
He was killed by his own car at his home in Los Angeles after it rolled down his steep driveway and pinned him against a brick postbox pillar and a security fence.
He'd played Pavel Chekov in Star Trek (2009) and Star Trek Into Darkness (2013) with his third film in the franchise, Star Trek Beyond, out next month.
