Simon Pegg has a message for longtime fans who weren’t wowed by the first trailer for next year’s Star Trek Beyond: The final movie will be less Beastie Boys and more true to the show.

“I didn’t love it because I know there’s a lot more to the film,” the actor — who also co-wrote the screenplay for Beyond — told British website HeyUGuys when asked about the trailer. “There’s a lot more story and a lot more character stuff and a lot more what I would call ’Star Trek stuff.’”

“I found it to be surprising,” said Pegg of the trailer’s “very action-packed” tone. “I found it to be the marketing people sort of saying, ‘Everybody come and see this film, it’s full of action and fun,’ when there’s a lot more to it than that. … You know, they’ve got to bring a big audience in, they’ve got to bang a drum. To the Star Trek fans out there, I’d say, ‘Hang in there, be patient.’ ”

They won’t have to be patient for too much longer; Star Trek Beyond opens July 22, 2016.
