Yelchin was mostly known for playing Chekov in the "Star Trek" reboot films but appeared in other major motion pictures such as "Alpha Dog," "Charlie Bartlett" and "Fright Night," to name a few.
The late actor was found pinned between a car and a mailbox pillar in his driveway at about 1 a.m. after friends said he failed to show up for a rehearsal meeting.
