Scarlett Johansson
She started her career in Hollywood at a very young age. She was going to get her first break in Robin William’s, Jumanji, but that role was reassigned to Kristen Dunst. So, Johansson persisted, didn’t give her up, and then after 3 years, she got another big opportunity to star in The Horse Whisperer.
