One might imagine that the short, witty "mockumentaries" that result from Christopher Guest's improvisational filmmaking style leave a lot of good footage on the cutting room floor. As the Best in Show DVD demonstrates, that assumption is correct. The DVD includes no less than 17 deleted scenes, some of which originally appeared on the film's promotional website, and many of which could have easily been included in the film without bloating its running time. It's clear that Guest's editing instincts were at their most ruthless when it came to his own scenes as low-key babbler Harlan Pepper, but each of the main characters shows up at least once in this section. A nice touch is that the scenes can all be viewed in succession without returning to the menu after each one. The DVD also includes information on eight cast members and one theatrical trailer. Guest's commentary with co-star and co-writer Eugene Levy is disappointingly sparse, considering their off-screen friendships with many of their castmates and the fact that they have five of the movie's credits between them. There are a few minor sound-related glitches, as actors' voices sometimes shift channels abruptly and for no clear reason. The best reason to own this DVD is the movie itself and the material that never made it to the big screen.
