I am looking for a movie, it's probably from the early 90's. I can't remember much but I remember a scene from the beginning that involves tossing young children down a slope into a fire (sounds bad I know), then there is another scene where there are these humanoid creatures that drop out of the trees and if you get enveloped in their membrane like wings they will digest you and only leave the bones. Anyone know it?

Sounds like,.

Beastmaster (82)
