Chris Pine Mourns 'Star Trek' Co-Star Anton Yelchin: 'I Will Miss Him'

— -- Chris Pine is speaking out about the death of his "Star Trek" co-star Anton Yelchin.

Yelchin, 27, was found dead June 19 in the driveway of his California home after being accidentally pinned by his own 2015 Jeep Grand Cherokee between a mailbox pillar and security fence.

Recently, Pine gathered the series' cast at his home to honor the life of their late pal, he said on ABC News' "Good Morning America" today.

"There's nothing that can prepare you for something that happens that quickly to someone who's that young," Pine said. "Nothing like that seems like it should happen. Our group, if anything, is a group of friends and family and it was nice to have them around to process what had happened and to pay tribute to who Anton was and to remember him and to smile and to cry and to ride the waves of grief. Our film is a wonderful example of what made him special. You hear the term 'light up the screen' and that's Anton. He's this bubbly, lovely, smiling -- just a lovable man and so, I will miss him."

Yelchin made his final appearance as Chekov in the latest feature, "Star Trek Beyond."

Pine stars as Captain James T. Kirk for the third time in the re-booted series.

"In the first two films he was very much kind of an angry, young man raging against the system that had taken his father," Pine said of his character. "Basically a man living in the shadow of his father. This film is really about James Kirk becoming his own man, individuating and finding his own way in the world."

"Star Trek Beyond" opens nationwide Friday.
