But, if Clooney has more money than he knows what to do with, why bother? Hang out on the beach and pick up hot girls.
I contend that he makes more movies for one of two reasons:
1. He just loves acting
2. He wants more money
If it's 1, he'd act for free(or cost). If it's 2, he doesn't have enough money and values that next dollar just as much as the others.
