Alma movie: Mr. Woodcock (2007)

John Farley (Seann William Scott) is a self-help author returning to his hometown to pick up an award. Now there's just one quirk not even his book can help him through: his former gym teacher and adversary, Jasper Woodcock (Billy Bob Thorton), is about to marry Farley's mom (Susan Sarandon). It's a battle of wits and hijinks, partly culminating with Farley publicly shaming Woodcock, and with Woodcock himself challenging him to a round of fisticuffs.
