- Billing Displacement: Tommy Lee Jones is first billed, although he does not appear until halfway though the film. Joan Chen, who plays the main character's mother, is billed second. Hiep Thi Le, who plays the actual main character, is billed tenth (with an "And Introducing" credit).
- Box Office Bomb: Budget, $33 million. Box office, $5,864,949.
- California Doubling: Vietnam was filmed in Thailand. Oliver Stone tried to get permission to film in Vietnam, but the communist government didn't like the scenes which portrayed the Viet Cong unsympathetically, never mind that every side is portrayed that way.
- Genre-Killer: The 1980s fad of Vietnam War movies came to an end with Heaven and Earth, which either killed the genre or confirmed that it was dead now.
