4. Jim Carrey

Jim Carrey didn’t just play underdogs—he lived it. After his father lost his job, his family lived in a van while moving between jobs, and Carrey worked nights as a janitor while still in school. These early struggles shaped his raw, emotional comedy.
He never gave up on his dream of making people laugh. His big break came with In Living Color and Ace Ventura: Pet Detective, launching a career of hit after hit. Carrey’s story is one of humor born from hardship.
