Actor Anton Yelchin, known for his roles in "Star Trek" and "Alpha Dog," was killed early Sunday morning after getting pinned by his own car ... TMZ has learned.
Yelchin's friends became alarmed because he was supposed to meet them hours earlier for a rehearsal. They went to his San Fernando Valley home at around 1 AM and found him pinned between his car and a brick mailbox, which was attached to a security gate.
