Feeling nostalgic about the Stars Wars trilogy (or perhaps nudging J.J. Abrams about his Episode 7 casting), Peter Mayhew, the actor who played Chewbacca in the original films, shared several behind-the-scenes photos from the set on his Twitter earlier this week. As io9 points out, the 65 photos came out between January 7 and January 9, and show everything from the cast hanging out between shoots to Carrie Fisher laughing with her stunt double, and even Harrison Ford having some fun with his props. See a few of the highlights below and catch the rest of the collection right here.
