Cameos galore. Carrie Fisher and Shannon Doherty have both filmed scenes for the film. Probably the most obscure appearance in the film happened totally by accident. Kevin Smith reported on his website that while filming at The Quick Stop which made him famous, Thomas, the roofer who discussed labor issues aboard The Death Star in Clerks, just happened to be buying milk. Smith had him to reprise his role in a “subtle but full-circle cameo.”
