"Big Fan", a new half-hour comedic game show based on "Jimmy Kimmel Live's" segment 'Who Knows?'. Each episode of the half-hour, studio-based game show will feature one celebrity and three of his or her biggest super fans. The super fans will go head-to-head to see who knows more about the episode's featured celebrity. The succeeding super fan will move on to the final round in an ultimate showdown, celebrity vs. super fan, to see who knows most about the celebrity. If the super fan wins, their prize is a priceless experience with the celebrity they admire most.
