Last night I watched Fanboys with Deb, and I recommend it for anyone who has any affinity for the Star Wars franchise. References abound, of course, but it goes beyond that. The group of friends razz and joke with each other brilliantly, and the cameos are something special too. I personally didn't recognise Billy Dee Williams (who played Lando Calrissian) at the time, but I did spot the three others. I don't think William Shatner portraying himself quite counts.

PS - The only disappointment was the apparent lack of special features on the DVD.
PPS - Not even a gag reel or commentary.
