The hotel where Will and Maya are staying is called "Edgerton," in reference of Harold Edgerton who was the inventor of the electronic flash.

The names of the SavMart employees announced over the in-store P.A. are all the names of famous photographers.

Robin Williams has the same last name in this as his character does in Jumanji; Parrish.

Jack Nicholson was originally cast as Sy and Robin Williams the manager at the mall, but Nicholson turned the role down and Williams requested Sy's role.

In the scene where the boss tells off Sy for being rude to the technican, you can see the photos of the employees on the wall. As we see later, Sy's photo is the one in the second row at the very right. In this first scene his photo is tilted while all other photos are perfectly straight. In another scene later in the same room, a security man holds the photo in his hands and asks for a copy. Both scenes were shot together and the photo was improperly put back to the wall, which explains why it is tilted in the preceding scene although it was not supposed to be taken off the wall by then.
