Even Chris Pine got in on the behind-the-scenes fun.
Weeks after his death, Anton Yelchin's co-stars are remembering his silly side.
Star Trek Beyond stars Jon Cho and Sofia Boutella took to Twitter to share some funny moments -- in the form of dubsmashes -- with the late actor on set of the sci-fi film.

Boutella was the first to share her silly dubsmash with the 27-year-old actor, posting a video of herself and Yelchin goofing off to Ice Cube's "Hello," on Thursday.
Cho later followed up with an epic dubsmash of his own. "It's all about…," he teased on Twitter, along with the video of himself lip-synching to Aretha Franklin's "Think" on set with Yelchin and Chris Pine.

The stars of Star Trek Beyond have kept Yelchin in their thoughts while gearing up for the film's upcoming release. Just last week, Zachary Quinto opened up on the loss during his appearance on The Late Show with Stephen Colbert.
"We genuinely love each other so much…but we are truly intertwined inextricably, and I think we always will be," Quinto said, explaining that the whole cast had become extremely close.
"I think our goal just has to be to celebrate his incredible life and honor him as much as we can. It was a terrible loss, not only to us, personally, but to the industry and to audiences," he added. "He was such a talent."
Yelchin died on June 19 -- the actor was struck by his car and pinned to a security fence in the driveway of his Los Angeles home.
