Brewster's Millions(1985)

You don't have to be crazy to blow 30 million dollars in 30 days. But it helps.

Monty Brewster, an aging minor-league baseball player, stands to inherit $300 million if he can successfully spend $30 million in 30 days without anything to show for it, and without telling anyone what he's up to... A task that's a lot harder than it sounds!
