Early 80s on HBO and I don't remember much. There were some creatures on an island or island resort in the jungle. The only thing I remember for sure is the end the main characters a man and woman are running to a helicopter and one of the things gets on and she starts to fall out and the movie just stops there.

Looks like your movie is probably Dance of the Dwarfs (http://en.wikipedia.org/wiki/Dance_of_the_Dwarfs_(film)).
