EXCLUSIVE: 'Star Trek Beyond' Promises Surprising Crew 'Revelations' -- Someone Has a Baby!

ET was first on the set of the new installment in the beloved sci-fi franchise.

The brand new trailer for Star Trek Beyond promises that the upcoming installment of the beloved sci-fi franchise is “where the frontier pushes back,” and ET has an exclusive look at what’s new on the Enterprise this time around.

Kevin Frazier was first on set and got an up close and personal look at the weapons bay from James T. Kirk himself (Chris Pine), who showed off some “brand new” phasers.

Karl Urban, who plays Dr. Leonard "Bones" McCoy, explained how the crew’s new uniforms pay tribute to the franchise.

“It's a little retro which I really like,” Urban told ET. “The designers have done a wonderful job of giving a lovely nod to Star Treks of the past.”

In Beyond, the Enterprise crew is two years into their mission to deep space, and Urban admitted that there is understandable “wear and tear on the ship.” John Cho, a.k.a. Sulu, explained that the crew is also starting to feel the strain.

“At the beginning of the movie, we're all homesick, we're all getting into our ruts and I think we've been around each other too long,” he said, revealing that for Sulu, that homesickness includes missing a heretofore unknown baby daughter.

“Sulu has a heartache for his little baby,” Cho divulged. “[He] had brought his picture to his console, which technically, we've been saying, it's unprofessional. It's in the way of the buttons.”

“She's a cutie,” the actor added of his on-screen daughter. “I got it out of a picture frame from Walgreens.”

According to Cho, there is “another revelation” in this film in regards to Sulu’s child, but “you’ll have to wait and see the movie.”

In fact things were so secretive on the set of the new film, directed by the Fast and the Furious franchise’s Justin Lin, that the studio resorted to some unique methods of keeping things under wraps.

“We got red scripts that have our names printed on them,” Urban revealed. “There are specific spelling mistakes incorporated into each draft, so that if it were to get out, they could still track it back to whose script it was.”

Star Trek Beyond is in theaters July 22, 2016.
