Leonardo DiCaprio ???

My buddy was hired to work on this as a crew member. He's a hired gun so he kind of goes where he gets the work and doesn't always know a ton about the project and he often comes into it in the middle or for only a few days. So he gets to set and is shocked to see this guy with his hat pulled down real low. It's Leonardo Dicaprio. He had no idea that Leonardo was a producer on it.
