Simon Pegg has revealed that his Star Trek co-stars went on a mission to party while shooting the latest movie together.
New recruit Benedict Cumberbatch joined Pegg, Chris Pine, Zachary Quinto, Zoe Saldana, director JJ Abrams and other stars of Star Trek Into Darkness at the premiere in London's Leicester Square tonight.
Fans went crazy for the Sherlock star, who plays villain John Harrison in the new sequel, giving him the loudest screams as he arrived on the white carpet, and the rest of the cast hailed his acting as out of this world.
Pegg revealed that the cast enjoyed a wild night out during filming.
He said: "We had one mad night out in San Francisco - me and Zach and Chris and Benedict - that will forever remain a secret but it was a lot of fun.
"But I wasn't the instigator. Can I just say, they're all as bad as each other. I don't even drink! Those guys, they were on their own mission!"
The film is the sequel to Abrams' 2009 big screen adaptation of the hit sci-fi series.
Saldana revealed that she was relieved Alice Eve had joined the cast, as a stowaway scientist on the Starship Enterprise, as she welcomed the female company.
She said: "Whenever the boys ignore you, you can always just call Alice. And then we'd chick out, like for two seconds be like 'Oh my God, I love your nails'."
She said of her male co-stars: "They're pretty cool nerds but they're all such geeks."
Star Trek Into Darkness is released in cinemas on Thursday 9 May.
