Where to ask about film scenes I can't recall?

[Male Navel]

Well i must have been like 14 or 15 and just realised i had this fetish. There was this movie set in the Amazonian forest or a tropical forest, and one in one scene one of the villains was standing at the top of a waterfall threatening to shoot a woman -one of the main characters, but she shot him first, it seemed RIGHT in the navel. He put his hand on his gut, managed to say "fucking bitch" and fell in the river. I cant recall the name of this film and what major actors were in it, but i want to rewatch this scene. It was an "Anaconda" type action film.
