Un chien Andalou (1928)
What is deceptive about this film?
It's a film that tries to do two things: to shock you, and to have no meaning whatsoever. Most films have a narrative, or at least a relationship between individual shots. Buñuel said the only rule he and Salvador Dalí followed when they were writing the script was that "no idea or image that might lend itself to a rational explanation of any kind would be accepted."
He also said that nothing in the film symbolizes anything.
