"If I was a part of 'Star Wars,' I don't know if I would speak on set," Pettyfer told Coming Soon. "I'm more of a fanboy."
Pettyfer added that he didn't want to mess with the series' success, and would much prefer to be able to experience "Episode VII" purely from a fan's standpoint, rather than as a participant.
"Those things, it's very weird for me, like I sometimes would prefer not to be a part of it, not in any disregard or disrespect, just because I'm such a lover of film -- to watch something like that is much more enjoyable for me," he said.
Pettyfer's fellow fanboys and -girls are no doubt growing anxious about who exactly *will* be in "Episode VII," with Gary Oldman recently revealing he was up for a part. Production is expected to start soon, so hopefully Abrams and co. will lift the veil of secrecy shortly.
"Star Wars: Episode VII" opens December 18, 2015.
