Trivia: When "Richard" starts to limp it wasn't planned, Harrison actually hurt a ligament in his knee shooting a promo for the movie, a promo that wasn't even part of the movie. He refused to receive treatment until filming was finished and ended up needing surgery.
Trivia: After his escape, it shows Harrison getting on a train marked with the name "Kimball" and then in the next shot, a helicopter flies over a hotel called "Harrison".
Trivia: On the cinema, VHS and pre-2001 DVD release of this film, an engineer can be seen looking down at Harrison Ford when the latter is taking shelter from the runaway derailed locomotive. Producer Peter MacGregor-Scott discusses this on an added feature on the new transfer DVD and says that the man has been erased digitally from the film. The odd thing is that the engineer, seen in closeup, bears a remarkable resemblance to Peter MacGregor-Scott himself and might even be him, judging by the latter's joking about the unwanted character in the film.
