Best in Show is a 2000 American mockumentary comedy film co-written (along with Eugene Levy) and directed by Christopher Guest. The film follows five entrants in a prestigious dog show and focuses on the slightly surreal interactions among the various owners and handlers as they travel to the show and then compete during the show. There are also short depictions of the characters six months after the show is over. Among the comedic aspects of the film are similarities between the personalities and characteristics of the owners and those of their dogs. Much of the dialogue was improvised. Many of the comic actors were also involved in Guest's other films, including This Is Spinal Tap, Waiting for Guffman, A Mighty Wind, For Your Consideration, and Mascots.
