The best actor in the world

Zach Galifianakis, to me the best actor ever. He plays parts in some of my favorite movies. Like the Hangover or the Campaign. He is very good at playing a dumb character. He is hilarious and is great at looking like he is messed up. He is a personal favorite of mine

I like him, because he puts a lot of effort into his acting and prepares for them in funny ways.
He will make separate bonus videos about how he gets ready and is some he will run around the building screaming they are hilarious.
