Much of Tom Lenk's dialogue during the Spry Gum commercial shoot was improvised by the actor. The voice heard off-camera belongs to Daryn Tufts, the director of the movie.
This was the first time that most of the cast, including Alyssa Milano, Christopher Gorham, Michael Landes, Carol Kane, and Tom Lenk, came to Utah to shoot a movie. Beau Bridges was the exception, who had worked in Utah before, most notably in The Other Side of the Mountain (1975).
During the golf scenes (30 min, 1:24 min) there is a horizontal line across the set that delineates the foreground from the fake background.
Before directing this movie, Daryn Tufts wrote and acted in a film entitled "Stalking Santa." The theatrical poster for this film is framed and hanging in Ethan's apartment. It can only be seen obscurely, in the living room, hanging next to the entrance to the kitchen.
