If you're an actor, then booking the lead role is a sign that you've truly "made it" in your chosen career path. Most actors spend years in bit parts and supporting roles, but some get lucky and land the lead role the first time they're cast in a movie or TV show.
Here are 20 actors whose first roles were lead roles:
