Bill Hader
Bill Hader might be known for his SNL impressions, but the actor is actually very anxious and has a lot of stage fright. He was performing a stand-up set at a friend's house in his backyard, and the whole crowd was enjoying the set. What he didn't realize is that a Saturday Night Live writer was in attendance and recommended Hader to go in for an audition. The casting directors loved him!
