The book has a completely different ending. There are no problems with the getaway, and they successfully get the gold back to England, and take it to Mr. Bridger, who tells them, "Now go and take it back to where you got it from!"
A MINI Cooper with two steering wheels was used for some of the shooting, in order for a stunt driver to actually drive the car while one of the actors performed in front of the camera. This unusual car is now a part of the MINI factory tour in Cowley, Oxfordshire, England.
