5. 'High Anxiety'
Alfred Hitchcock's last movie is technically 1976's Family Plot, but the following year he sat down with Mel Brooks and helped him write the spoof movie High Anxiety. "He said, 'What are you going to do about The Birds?'" Brooks recalled in 2013. "I said, 'Well, gee, at the moment I haven't included it.' And he said, 'Well, why don't you have them attack you with ... their doody? If they all shit all over you, I mean, it's going to be funny.' I said, 'Thank you. Thank you, Mr. Hitchcock.'" The movie is a spoof of the entire Hitchcock filmography, and it earned $31.1 million at the box office.
