It is FAR harder to play less intelligent than you are. I cannot stress how much more difficult it is.

Actors are more so than any other profession than I have been in except, perhaps, teaching... varied. This is true of basic wisdom, intelligence, how articulate they are, how well read they are, how well they comprehend what they read, how well educated they are, etc.
A lot of actors are total idiots, many are some of the most amazing minds I have encountered, and you would really be surprised whom each are.
