From the writer of The Wrestler comes this darkly comedic character study that explores the obsessive world of professional sports fandom. Patton Oswalt delivers a career-defining performance as Paul Aufiero, a thirty-something parking lot attendant living with his mother on Staten Island, whose entire existence revolves around the New York Giants and his idol, linebacker Quantrell Bishop. By night, he calls into a local sports radio show to defend his team, and by day, he navigates a life of quiet desperation. Paul's world is thrown into chaos when a chance encounter with his hero takes a violent turn, forcing him to confront the devastating gap between his fantasies and reality. Directed by Robert Siegel, the film walks a razor-thin line between sympathy and satire, painting a poignant portrait of a man who has invested everything in a one-sided relationship with fame. As Paul faces an impossible choice between his loyalty to the team and his own dignity, Big Fan becomes a deeply human exploration of identity, obsession, and the lengths people go to find meaning in their lives.
