Back to the Future + E.T.
Time Out says
What better way for a double feature than an '80s flashback session at the cinema? Getting the double feature going is Spielberg-produced, Zemeckis-directed ‘Back to the Future’, where Michael J. Fox's Marty McFly is lost in the past and has to find his way back without changing the course of the future forever. And then it's the next fish-out-of-water film with ‘E.T. the Extra-Terrestrial’, all about an alien who gets left behind on Earth and is taken in by a boy and his family, changing them all forever.
