I came to this thought that E.T. was in fact a Jedi (or at least Force-sensitive) and the more I think about it, the more it seems possible. This would explain many things.
First, we already know that E.T came from the Star Wars Galaxy.
So, if he was a Jedi, he would show some force powers:
- Force healing and/or Plant Surge when he revived a Flower.
- Hibernation trance may explain his recovery.
- Telekinesis to lift him, Eliot and their Bike into the air and toward the forest.
- Lumos for his finger light (ok, I'm mixing universes on this one, it probably has a biological explanation.)
So, the only thing left is to determine if all others member of E.T.'s species (Children of the Green Planet) possess those powers. I hope we could find this information in "E.T.: The Book of the Green Planet" (a book from E.T. franchise which is the sequel to movie's novelization).
