Between the better known comedies Airplane! and The Naked Gun: From the Files of Police Squad!, David Zucker, Jerry Zucker, and Jim Abrahams made Top Secret!, a send-up of Elvis Presley and espionage pictures all at once. Like most of their comedies, half of them don't work and too many of them cross the line of good taste, but there are still enough gags that work that it's funny almost straight through.
