Blank Check (1994)

Bullied by his siblings and nagged by his parents, 11-year-old Preston 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 gives the boy a blank check as compensation. Preston makes the check out for $1 million and goes on a spending spree he'll never forget. Maybe now, his family will take him seriously!
