Trivia: Throughout the film there are several references to a character named Horseflesh, (such as "Horseflesh would never get us into this mess"). Despite the character being credited at the end of the movie he's never properly shown onscreen. There's a paragraph devoted to him in the published "Time Bandits" screenplay: "The trouble is quite frankly that if Horseflesh had been in it he would have made seven dwarves, and we'd have libel suits from Disney and all sorts of things. But we liked the name, so he remains the mystery dwarf." According to the interview with Michael Palin and Terry Gilliam on the extras DVD (produced in 2002), Terry Gilliam states that Horseflesh is the dwarf seen with Evil, though it isn't mentioned who he is; in the original script he had quite a few lines, but they were cut, eg "The map! Evil one, the very map I promised you, is yours" (from script excerpt shown on DVD).
Trivia: When Betty and Ollie are talking in their office (and Ralph and Macy come in), look carefully at the table all the way to the left.
