Force Awakens cast not all played my mo-cap Serkis

“I can say I play only one character,” Serkis tells Entertainment Weekly, submitting to a typically guarded interview that sees the actor sharing “10 things” about his role, provided you count knowing that he wasn’t there to see Ford get injured, or that people were really interested in spying on the set.” As for the few actual, somewhat informative things, Serkis confirmed again that it is his unaltered voice heard in the trailer (“There’s no digital manipulation. That’s just me”), and that it is the voice of his character: a motion-captured recreation of Benedict Cumberbatch.
