All-Star Cast: As mentioned above, this movie has quite a few big names in it, although some of them could be considered to not have really made it big until after this movie.
Deleted Scene: When shown on TV, there's some new content. This includes the start of a day at Luger's house (complete with his promiscuous daughter hiding a guy she slept with the previous night), a scene towards the end where Colt has an out-of-body experience, and many more. As with The Naked Gun, these scenes are unfortunately left out of the DVD release.
Hey, It's That Voice!: The Japanese dubbed version deserves a special mention: The movie got two different dubs from two different voice casts. While this is not unusual in Japan, especially when dealing with foreign series and movies broadcasted in different networks and media (VHS, DVD, BD, etc), the Japanese dub has the unusual case they dubbed the film in two of the most known accents in Japanese media: the standard Japanese accent (Kanto-ben) and the Kansai Regional Accent. the Kanto-ben version used professional voice actors, while the Kansai one used comedians instead, and taking into account the stereotypes associated with that accent, it's very possible the Kansai version was a Gag Dub.
Stillborn Franchise: Apparently, a sequel was planned, but the first movie only made $28 million at the box office, so the plans were scrapped.
Throw It In: Dr. Leacher falling flat on his face while restrained was not performed by a stuntman. This is the actual actor accidentally falling down and hurting himself. The director found it too funny to pass up and included it in the movie.
