Foundations of Analysis - The Movie

This actually happened about 15 years ago, when -- as a young lecturer -- I was asked to give a course on Foundations of Analysis. I was sure at the time that the students already know the subject matter and they will be wasting their time listening to me. I was quite surprised, when I entered the classroom for the first lecture, to find a room packed with students. I was going to suggest that those who know the subject matter leave the course, so as not to waste time and energy. I therefore asked the following question: "Has any one of you, by chance, read the book of Landau: Foundations of Analysis?"

The class suddenly became very quiet, until a student from the last row said: "I did not read the book, but I saw the movie." Weeks later we were laughing, trying to imagine to ourselves how a movie on Foundation of Analysis could look like.
