This is done really well. 

Envoy



Part E.T., part Iron Giant, and part just really good, "Envoy" is an excellent 10-minute short film by David Weinstein, which he hopes will work as a proof-of-concept video for a feature-length movie. It starts a little slow, but keep watching and you'll be treated to a solid short with some damn fine VFX.

I would mind if someone actually funded a full movie of this in the slightest. You can get more details on the project over at the official site.
