Although not credited, Eric Stoltz played one of the guests at the table when Deforest (James Spader), Rachel (Ione Skye), and Charles (Dexter Fletcher) go to the café.
The computer used by Dexter Fletcher throughout this movie is a Commodore Amiga A500, a U.S.-made computer that didn't do very well in the U.S., but was very popular in Europe.
There is a scene towards the end in which Rachel (Ione Skye) is seen through an aquarium. This was the inspiration for the iconic romantic scene featuring Claire Danes as Juliet in Romeo + Juliet (1996).
