Steve Martin is one of my favorite actors. He is an impressively intelligent man yet is famous for stupid slapstick. Someone once said, Steve Martin does stupid humor for smart people, and I think that's right.
The Jerk is simply an all-time classic. Roxanne is also fantastic. And Bowfinger is ultra-clever.
In recent years he's done some formulaic family comedies, but he's done them well.
One of the best American comedians of all-time.
