John Carpenter's Starman

STARMAN is a story of romance and adventure, as an alien (Jeff Bridges) observing life on Earth becomes stranded near the Wisconsin farmhouse of recently widowed Jenny Hayden (Karen Allen). The alien, otherwise known as Starman, clones the human form of Scott Hayden, Jenny's deceased husband. Due to be picked up by his mother ship in three days at Meteor Crater, Arizona, Starman is in dire need of human assistance. Thus Jenny becomes an unwilling participant in a trip that becomes a dangerous flight across the U.S. as the two are pursued by the U.S. Army and secretly aided by a government agent (Charles Martin Smith). Over the three-day journey, however, a strange and wonderful relationship develops between a confused human woman and a curious and determined alien, leading to a climactic rendezvous with Starman's mother ship.
