Blank Check (1994)

Bullied by his siblings and nagged by his parents, 11-year-old Preston Waters is fed up with his family — especially their frugality. But he gets his chance to teach them a lesson when a money-laundering criminal nearly bulldozes Preston with his car and compensates the boy with a blank check. Preston makes the check out for $1 million and goes on a spending spree he'll never forget.
