Pol Pot - he rounded up anybody he thought was intellectual and had them executed. And how he told someone was intellectual or not was whether they wore glasses. If they're that clever, take them off when they see him coming!
I do dumb stuff, like playing my favorite dumb Barry White song and lip-synching into the mirror so it looks like his voice is coming out of my mouth.
And my first film was Carnal Knowledge, another amazing experience, largely because of Mike Nichols, who would tell me you can't do anything wrong because you're doing everything right.
