According to Pat Proft, had a second season been commissioned, the spot in the opening credits where Abraham Lincoln was shot at, and retaliates with a pistol would have been replaced by a similar one, featuring Mohandas K. Gandhi and a machine gun. This joke was later used in a fake trailer for "Gandhi II" in "Weird Al" Yankovic's UHF (1989).
Det. Frank Drebin:
Various: Yes, I know.
The opening credits always has a guest star who immediately gets killed off in some silly way.
The series' Hungarian dubbing changed Frank Drebin's last name to Drebil. This could have been either a simple mishearing, but it might be a joke on the translator's part, as the name sounds similar to the French-derived word "débile" or "debil" (meaning stupid or retarded). In the Hungarian release of the Naked Gun films based on the series, his name was changed back to Drebin.
