The Gambler (2014)

Literature professor Jim Bennett (Mark Wahlberg) leads a secret life as a high-stakes gambler. Always a risk-taker, Bennett bets it all when he borrows from a gangster and offers his own life as collateral. Staying one step ahead, he pits his creditor against the operator of an illicit gambling ring while garnering the attention of Frank (John Goodman), a paternalistic loan shark. As his relationship with a student (Brie Larson) deepens, Bennett must risk everything for a second chance.
