So this movie has come across my mind many times. I can’t for the life of me remember it. It’s an 80’s or 90’s movie. In English and color and it has to deal with a half fish or amphibian of some sort and half human. He also has a romance with a female type of the same species. I think they interact with humans. And the scene I remember most is them fight off other people in a cave. I’m not sure if they have their own language or what the deal was. I really wish I could remember this movie. Only saw it a few times and if I could only find a picture of the guys face I would know exactly what the movie was. Please help!!!
