"I'm No Angel" is one of the most important films of the controversial Mae West, the actress who saved Paramount Pictures from bankruptcy after the Great Depression. This actress was responsible for the censorship code in Hollywood and her malicious quotes are great. For example, "When I'm Good, I'm Very Good. But, When I'm Bad... I'm Better"; or the song "No One Does It Like a Dallas Man", that was forced to be changed "No One Loves Me Like a Dallas Man". My vote is seven.
Title (Brazil): "Santa Não Sou" ("Saint I am not")
