Query: Where did they get the idea for this movie?

I recently read a book written by Richard Feynman a physicist who worked on the atomic bomb. His book entitled 'Surely you must be joking Mr. Feynman' has numerous (and quite funny) true stories from his life. One chapter is about how he was going to take vacation somewhere in South America. His friend heard he was going there and got him a job in Brazil teaching students at The Center for Physical Reasearch. When he got to Rio he did a television spot with Cesar Lattes - the the director of the Center for Physical Reasearch. They filmed without sound, and they asked the two of them just to look as is they were talking. So Lattes asked Feynman "Have you found a sleeping dictionary yet?" He was of course asking if he had found a girl to sleep with.I wonder if the writer of this movie or book got the idea from Feynmans story?
