2. Igor - Young Frankenstein
Igor is hands-down the best thing about this movie. From his hunchback that mysteriously switches sides throughout the movie and his sassiness over the pronunciation of his name, to his complete lack of ability to play charades, he is a gem of a character that Marty Feldman brings to life. He's such a clever play on the traditional "Yes, Master" caricature of Igor, and it's probably one of the most well-executed aspects of the satire in this film. A huge part of the credit has to be given to Feldman, because he somehow manages to make every single line laugh-out-loud funny. As much as I love Gene Wilder as Frankenstein, I have to admit that Marty Feldman steals the show.
