Big Fan is a 2009 American dramedy film written and directed by Robert D. Siegel, and starring Patton Oswalt, Kevin Corrigan, Marcia Jean Kurtz, Michael Rapaport, and Scott Ferrall.

The story revolves around the bleak yet amiable life of the self-described "world's biggest New York Giants fan",[2] Paul Aufiero (Oswalt).

Paul is also a regular caller to the Sports Dogg's radio talk show, where he refers to himself as "Paul from Staten Island", rants in support of the Giants, and berates his on-air rival, Philadelphia Eagles fanatic "Philadelphia Phil".

Phil, lying shocked on the men's room floor, stares at his hands, which are now covered in red and blue, the Giants' colors.

Sal visits Paul in jail and reveals to him the Giants' schedule for the following season.

The website's critical consensus reads, "Featuring Patton Oswalt's sympathetic portrayal, Big Fan humorously and effectively captures the dark and lonely world of a sports fanatic.

"[4] Metacritic gives the film a score of 70 out of 100, based on 27 critics, indicating "generally favorable reviews".
