- Actor Allusion: Dan Aykroyd plays Lucy's neuro-physician, who mentions that their clinic is funded by TB Callahan in Sandusky, Ohio, yes, he'd know all about that.
- California Doubling: Mostly averted: While most of the movie was filmed in Hawaii, a couple (such as the walrus tank scene) were filmed in California.
- Dyeing for Your Art: Rob Schneider gained weight and underwent a makeover to become nearly unrecognizable as Ula.
- Playing Against Type: Roger Ebert goes to great lengths in his positive review mentioning how likable Adam Sandler ends up being due to not being the Sandler role of a manchild, someone with anger issues, and/or someone with an annoying lisp.
- Throw It In!: The penguin wasn't supposed to close the gate twice. That was a mistake, but the filmmakers left it in for humour.
