According to an inside source for IGN Middle East, actor Simon Pegg was on the set J.J. Abrams' Star Wars: Episode VII in Abu Dhabi. The source claims that the actor has a secret role in the film. We weren't expecting this news, especially after the actor had this to say in a previous interview when he was asked if he would be in the film:
“I don’t think it would be appropriate for me to be in it, to be honest. I think J.J. should cast new faces with no stunt casting.”
Maybe that was just one of those things he said to throw people off the scent of what really is going on. Pegg has a history with Abrams and has had roles in his films such as Star Trek and Mission: Impossible III. On top of that, the actor is a HUGE Star Wars fan, so it doesn't seem too far fetched to think that Abrams might have given him a small role in the movie.
This is all unconfirmed at the moment, so treat it as a rumor that you should take with a grain of salt. if Pegg does end up in the film… awesome! If not, I'm sure the movie is going to be just as great.
