- Nick Nolte wore a back brace during much of the filming to maintain a rigid Marine posture.
- The scene on the railroad tracks is a reference to the final adventure in Mexico of beatnik figure Neal Cassady, Jack Kerouac's inspiration for Dean Moriarty in "On the Road". Author Robert Stone had traveled with Cassady and Ken Kesey's Merry Pranksters. Nolte was in the midst of extensive research on Cassady for his portrayal in the film "Heartbeat".
