Revealing mistake: When Buddy love and Stella are standing at the lookout above LA, the background is obviously a poorly done painting.
The Nutty Professor (1963)
1 revealing mistake
Directed by: Jerry Lewis
Starring: Jerry Lewis, Stella Stevens, Del Moore, Kathleen Freeman
Continuity mistake: In the beginning, Jerry Lewis makes his special drink and it is the consistency of a milk-shake. Later in the movie he makes the same drink and it looks like cloudy water.
Dr. Hamius R. Warfield: Kelp, it's human nature. Kelp, people just don't like teachers blowing up their kids.
Trivia: When Professor Kelp holds the pile of tests and fantasizes about Stella as she stands in the doorway waiting for the stream of students, the test facing the camera has a caricature of Jerry Lewis. (00:52:20)
