According to Writer and Director Peter Greenaway, there are one hundred things beginning with the letter "s" in Smut's (Jason Edwards') room and one hundred things beginning with the letter "m" in Madgett's (Bernard Hill's) room.
The words "kiss me hard" appeared on a sheet of paper in a typewriter. This was probably a reference to Admiral Lord Nelson's death at sea, when his last words were "Kiss me, Hardy".
The painting in Madgett's room is that of Peter Bruegel's "Children's Games".
The license number plate on Madgett's car is NID-26 B/W, same as the crashed car in the beginning of A Zed & Two Noughts (1985).
Inspired the structure of the story "24 Hours" in Neil Gaiman's comic book The Sandman (issue #6) (1989). Mentioned in Entertainment Weekly issue 1487/88.
