Long Walk to Forever (lost short film; 1987)
From The Lost Media Wiki
Long Walk to Forever was a 1987 short film based on a short story by Kurt Vonnegut about a soldier who leaves the army to convince his girlfriend to marry him. It is known for being the first film role for comedian Denis Leary.
Despite the fact that both Vonnegut and Leary were involved, the movie doesn't seem to have any available copies on the Internet or elsewhere, making it incredibly hard to find for people who might have wanted to see it either to see Leary's debut or if they were Vonnegut fans. Leary would later gain fame after ranting about R.E.M. for an MTV sketch in the 1990s.
