I remember when I was about 12 sneaking downstairs one night and watching this odd movie.
A group of people (perhaps this may even be two movies?), stole a suitcase full of money. I think they were on a plane and it crashed on an island. Everyone was trying to get the suitcase of money, when suddenly headhunters started to kill them off. Eventually a handful of them get off this island and are standing on a bridge. A woman was holding the suitcase when a man kissed her, grabbed the suitcase and pushed her off the bridge to the water below.
Sorry I'm a little hazy on the details this was over 20 years ago, but I am still trying to figure out what the movie was called. I remember being terrified of the headhunters!
