Nothing Lasts Forever is a 1984 American science-fiction comedy film directed by Tom Schiller. Shortly before its intended release date of September 1984, Metro-Goldwyn-Mayer postponed it. The film has never been officially released theatrically or for home media in the United States. It was eventually broadcast on Warner's cable TV network Turner Classic Movies.

It stars Zach Galligan and Lauren Tom in the lead roles, with a supporting cast including Bill Murray, Dan Aykroyd, Sam Jaffe and Mort Sahl. John Belushi was to appear in the film, but he died six weeks before production began.

An artist fails a test and is required to direct traffic in New York City's Holland Tunnel. He winds up falling in love with a beautiful woman, after he takes a trip to the moon on a Lunar Cruiser.
