I have to give credit to Robert Siegel and his screenplays. Big Fan and The Wrestler are both original and well-thought out Greek tragedies content with minimizing cliches. His films underscore the heros' tragic flaws and spiraling ritual of self-destruction.
In Siegel's premier as a director (he only wrote The Wrestler and The Onion Movie), Patton Oswalt stars as a man-child who lives with his mother and works as a parking garage attendant. Oswalt must deal with his family—one brother who is a successful personal injury lawyer married to a buxom trophy wife, and a sister who is married to a husband who helps run a wholesale club store—and their insistence that he making something of himself. He is content in his life, being a fanatic of the New York Giants and spending his time at work listening to sports talk radio and writing mini-manifestos, which he calls in to refute his on-air nemesis, Philadelphia Phil, late at night—much to the annoyance of his mother. He and his equally schlubbish best friend, played by Kevin Corrigan, obsess over each game and play. Oswalt idolizes the Giants' star linebacker, Quantrell Bishop. Corrigan and Oswalt are like grown up children, though being well into their thirties, as they excitedly base their lives around the Giants' sixteen-game season. They even go to the Meadowlands to watch the game on TV in the parking lot.
As the season starts winding down, with the Giants in the NFC East lead (being tailed by the Philadelphia Eagles), Oswalt and Corrigan are lucky enough to spot their hero linebacker one night. They follow him and his posse, ending up in a club. They finally work up the balls to go and say hi, but the meeting turns violently when they accidently let slip they have been tailing Bishop across the city. Despite efforts by his friends to diffuse the situation, Bishop, like any self-respecting 'roided up athlete, beats Oswalt to a pulp and sends him to the hospital in a coma. Things begin to close in on Oswalt as Bishop has been suspended and the police want information about the incident so the can press charges. Oswalt's brother wants to sue the player and initiates a lawsuit.
Big Fan is not unlike the situation in Forgetting Sarah Marshall, where Jonah Hill meets and pesters Russell Brand's Adolous Snow, except it didn't end with Brand beating the shit out of Hill. Big Fan has a view on our obsession with people who play glorified children's games, yet get paid millions of dollars. How we let our favorite celebrities practically get away with anything.
