Natalie Portman – Léon: The Professional

Actress Natalie Portman was just 12-years-old when she starred her carer as the young protégée of a hitman in the action film Léon: The Professional. While Portman now considers the film “inappropriate” and “problematic,” there’s no question that it made her into one of the most famous child stars of all time.

Since hitting it big at the age of 12, Portman has continued to work hard in Hollywood, starring in everything from Star Wars to Black Swan. She even managed to find the time to graduate from Harvard University! Now, Portman is heading back to the Marvel Cinematic Universe for the next Thor film.
