Croupier (1998)

Jack Manfred, a writer struggling to stay afloat, descends into the intoxicating world of casino life, accepting a position as a croupier. Initially, he observes with detached cynicism, convinced of life's inherent gamble and the gambler's inevitable fall. Yet, the allure of the casino proves too strong. Drawn into its seductive embrace, Jack finds himself consumed by the high-stakes environment. His relationships fracture under the pressure, and the novel he once dreamed of writing slowly slips from his grasp, a casualty of his dangerous game. The casino's allure proves a siren song, leading him toward ruin.
