'Star Trek' Fights 'Exhausting And Exhilarating' For Benedict Cumberbatch

'I was dragged up to a standard — to his standard — by the most extraordinary experts,' actor tells MTV News of 'Into Darkness.'

In "Star Trek Into Darkness," Benedict Cumberbatch plays a mysterious newcomer who quickly finds himself facing off against the crew of the Enterprise. In an epic fight scene with Mr. Spock himself, Zachary Quinto, Cumberbatch says he wore himself out even before he actually got on set to shoot the sequence.

"It was exhausting but so exhilarating," Cumberbatch told MTV News last week. "These guys had been training a little bit longer than I had, because I was late to the process of being part of the film. But one of the best parts was the fight rehearsals with Zach and our amazing, amazing stunt doubles. I was dragged up to a standard — to his standard — by the most extraordinary experts."

Director J.J. Abrams sat in the director's chair for the franchise for the second time on "Into Darkness," but even he admitted that the sequence turned out more impressively than he had expected. "The fun of it was to shoot it outside with this built piece of this ship with actual wind and smoke and the sun," Abrams explained.

"Star Trek Into Darkness" stars Zachary Quinto and Chris Pine form a real-life odd couple.

"It ended up looking so crazy real even before we did the visual effects," he observed. "The sun was huge, but we got the camera movement on such a grand scale so you knew you weren't on a stage. I mean, it was a really crazy thing to shoot."

Quinto revealed that they shot the sequence on just one moving platform, but in the film, it looks like he and Cumberbatch square off on two. He admitted that seeing the end result took his breath away. "It's that kind of stuff where you look at the movie that you're in and go, I don't get it," he said.
