Nothing Lasts Forever is a 1984 American science fiction comedy-drama film written and 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 on home media in the United States, though it was eventually broadcast on Turner Classic Movies. The movie was once uploaded onto YouTube, but was taken down at the insistence of Turner Entertainment, the copyright owner of the pre-1986 MGM film library.

I was reading about this in a book about Bill Murray just the other day. Apparently, Murray used some time off while he was filming Tootsie to appear in this.
