Here we have another big-time actor that started out when they were just a kid. Scarlett Johansson has starred in so many good movies, it's really hard to keep track of them all. In fact, she is consistently featured in lists of the world's highest paid actresses and has amassed a fortune worth over $100 million. If that's not a sign of Hollywood success, we don't know what is!
She scored her first major film role as a 12-year-old in Manny & Lo, and two years later she was starring opposite Robert Redford in The Horse Whisperer. In 2001, when she was 17, she starred in Ghost World, which really put her in the spotlight as a serious actress. Since then we've loved her in Lost in Translation, Vicky Cristina Barcelona, He's Just Not That Into You, and so many more.
