Based on a story by Steven Spielberg.
Now, at last, we see where E.T. comes from - who he really is and what his own distant world is like. Return with him to the Green Planet, whose inhabitants are the supreme masters of all growing things in the galaxy. Wander through their immense enchanted gardens, to which E.T. has returned, with Gertie's geranium, a fondness for junk food, and an all-consuming love for the earthling Elliott and his family.
But things on Earth have changed since E.T. left. Elliott has begun to notice the opposite sex, and his cherished memories of E.T. are losing ground to thoughts of a girl in his class who wears a rhinestone ponytail clip. More important, he seems to have forgotten E.T.'s teachings of gentleness and peace.
"He is about to become the most terrible thing of all," observes E.T. from three million light years away. "He is about to become - Man."
