HI! I'm trying to find out what this film is called... There are white creatures a bit like gorillas, trying to kill people in the jungle. The people are protected by a laser beam force field, which breaks at one point. There are hundreds of caves where these creatures live. The film must be about 15 years old. I can't actually remember what else happens, but it was very scary when I was little! Please help me, this is driving me crazy! Thanks.
