Trivia: The closing credits (the fake freeze frame and the journey on top of the car roof) are tributes to Police Squad (the TV series on which the Naked Gun films are based), which used those themes as the closing and opening credits (respectively) in each episode.
Trivia: When Richard Cane is thrown from his motorcycle and lands in a fountain, he yells a Wilhelm scream.
Trivia: Despite playing mother and son, Priscilla Presley is only 7 years older than Liam Neeson. Frank Drebin Jr. was also born at the end of The Naked Gun 33 1/3: The Final Insult, which was presumably in 1994, when the film was released. So unless the writers are completely disregarding the franchise timeline, that would mean 73-year-old Liam Neeson is playing a man in his early thirties.
