What is this movie???? Pls

Okay… So this one is a hard one I guess. I dont recall very much from it, but it annoys the **** out of me. At first I thought it was Avatar, but I just watched that and it wasn’t it.

I think it’s set on another planet (Like avatar) and i recall that the people are living in “houses” attached to the mountain on that planet. Tree-like-houses. Then a human comes to the planet and becomes friends with one of the natives and the only thing I remember is the native telling the human that they don’t use time. Time is not a thing. They just do what they want, when they want. I don’t know if it’s an animated or “real” movie. Please help, it’s driving me nuts!
