The two friends and collaborators had hidden little nods to each other’s films in their work before, but for E.T., Spielberg didn’t need to hide anything at all. In one of the film’s cheekiest jokes, E.T. sees a child dressed up as Yoda for Halloween, prompting the little alien to exclaim, “Home! Home!” Spielberg didn’t tell Lucas about the joke until he held a personal screening for his friend at his Skywalker Ranch, which Lucas approved of with laughter. When he went on to make The Phantom Menace, Lucas returned the favor and made E.T.’s race of aliens part of the Galactic Senate. You can see them acting uncharacteristically hostile in the video above.
