When I was younger, I saw a movie at the drive-in, so let's say early 70's. The movie had a funnny/chase theme, but what made it different was that it literally ended in a cliffhanger - the gold on one end of the bus with the people on the other, teetering on the edge of a canyon or something. I have no idea of actors or anything else, just the ending was a cliffhanger. I'd like to see it again, if I can first find the name of the movie. Can you help?
