Who do you want in Fargo?

I freaking love this show. Both seasons are fantastic television that I recommend to everyone. Easily my favorite show on tv right now. The casts of both seasons are FANASTIC. I'm very intrigued about Ewan McGregor to be in season. Who are some actors you would like to see step into Fargo? For some reason, I really want to see Malcolm McDowell on the show at some point. He's just a really charismatic actor, and I think he could bring a different flavor to what we've seen so far. I could see him as some kind of crime boss. Or maybe some stuffy prick in town that nobody likes, and something terrible happens to him. I don't know. Is there anyone that you would love to see on this show?
