I don't remember much of the movie. But I know it had chimps learning to fly I think . The chimps can sign and a guy learns to say apple in sign language. If anyone has any ideas I would appreciate it.

Project X (1987) starring Mathew Broderick.

Farout I was only thinking about that movie today believe it or not. It most certain project X. Fantastic movie.

Yeah, it had Helen Hunt in it too, right?
