Movie E.T. and Elliot: they are sort of ambiguously best friends, with slight undertones of Elliot loving E.T. like a boy loves his childhood dog.
Book E.T. and Elliot: E.T. is a directly depicted father figure to Elliot, but believes Elliot is also a father figure to him in return. Also he gives Elliot like a full ego death via telepathic link and accidental exposure to infinite celestial knowledge that briefly shatters the young boys psyche.
