While none of the actors are able to tell us much about The Force Awakens yet, in an interview with Entertainment Weekly Andy Serkis shared a few things that he can tell us about the movie and his work on it. His answers to EW’s questions, unsurprisingly, don’t give us a lot of detail about the story or characters, but he does reveal that he plays only one character in the film and that his voice in the teaser is unaltered.

One question that he’s not able to give an answer to is whether or not his character is performance capture, which is unsurprising, given the amount of information one could likely draw from the answer.
