This is the only "Santa Clause" movie where Santa's Head Elf Bernard doesn't make an appearance. David Krumholtz wasn't available since his Numbers schedule conflicted with the filming. Because of this, the script was written with the returning character Curtis having taken over as the Head Elf.
Peter Boyle played Mr. Whittle, Scott Calvin's supervisor in the first movie, then was recast as Father Time in the later movies.
The scrolling ticker sign in the toy factory reads "378 Years without an accident."
Spencer Breslin's sister Abigail Breslin appears as Trish, one of the elf students in Mrs. Claus's class.
Despite Bernard's non-appearance in the film, the novelization uses his character.
