Brewster's Millions (1985)

Richard Pryor is Montgomery Brewster, a minor league baseball pitcher who discovers he has to blow $30 million in 30 days as a condition to inherit a much greater fortune. Here's the catch: He will forfeit everything if he reveals to a soul the real reason he seems to be throwing away all that cash. With the help of his pal Spike (John Candy), they set off on a frantic spending spree the likes of which would bring any self-respecting accountant to his knees.
