4. Mickey Rooney - Breakfast At Tiffany's
Rooney's controversial portrayal of Mr. Yunioshi in this classic comedy almost threatens to completely derail the entire movie. Not only did it court controversy for it's possible racism, it was also frankly hideous to watch and felt ridiculously out of place in the context of the film, which is stylish and witty throughout. Really uncomfortable viewing then and even more so now, Rooney's performance stopped Breakfast At Tiffany's from being remembered for it's virtues.
