I’ve seen this movie and loved it and want to watch it with a friend but can’t remember name of it. Can’t remember lots of details either. I’ll describe one scene. There’s a great scene on the ocean floor. A man and woman doing a dance duet. Very graceful yet funny. Surreal, comic feel to the scene. I believe the woman had emerged from a giant clamshell. The man is in love with the woman and much of the movie is about his pursuit of her. If I remember correctly she is a mermaid or mermaid-like.
