Comic Book: the Movie

Comic Book: the Movie is directed by and stars Mark Hamill. This is something of a light mockumentary about how comic book fandom and the Hollywood movie industry meet. Hamill plays a comic book shop owner hired to act as an advisor for a studio making a movie based on his primary comic love: Commander Courage. They have given him a crew to document the announcement of the movie at that year's ComicCon in San Diego.
The movie is low budget but pretty fascinating. One of the more interesting aspects of it is that there are segments of the movie that are largely improv as they just walk about ComicCon, totally in character. It's a little less plain goofy than This is Spinal Tap but much of the humor is in the same vein and works quite well. I give the movie a B+.
