The actor's name is Steve Buscemi. I think he was chosen for a couple of reasons, both of which mean that for people familiar with his work he was the ideal choice. One reason might be because he's often played whiney, demanding, insecure characters, another might be because of the way he looks, which a little strange in a funny way...Some of those "You're not you when you're hungry" commercials are hilarious Putting Danny Trejo in a Brady Bunch scene is comical lol. I don't get the last part of the commercial though. Who is that who says Marsha Marsha Marsha and why is it funny? It makes me laugh but since I don't know who the actor is, I don't really get why its funny.
