William H. Macy, 59 today!
From the IMDB entry for Fargo:
William H. Macy begged the directors for the role of Jerry Lundegaard. He did two readings for the part, and became convinced he was the best man for the role. When the Coens didn't get back to him, he flew to New York (where they were starting production) and said, "I'm very, very worried that you are going to screw up this movie by giving this role to somebody else. It's my role, and I'll shoot your dogs if you don't give it to me." He was joking, of course.
