- Beam Me Up, Scotty!: Wording which appeared to be a quote by George C. Scott from the film was boldly publicized in a massive font size as the film's main Tagline on movie posters. It said: "Oh my God, that's my daughter!". However, Scott doesn't actually ever say this in the movie.
- Completely Different Title: The movie was retitled The Hardcore Life for its British theatrical release in the UK. On the Australian 1980s home-video release this phrase ran as a kind of subtitle under the movie's Hardcore title logo.
- Executive Meddling: Paul Schrader's first choice to play Niki was real-life adult actress Marilyn Chambers, who had begun dabbling in mainstream acting starting with David Cronenberg's Rabid. He was vetoed by the producers who, ironically, thought she didn't look enough like a porn actress.
- Hostility on the Set: George C. Scott and Paul Schrader did not get along, so much that at one point Scott refused to come out of his trailer and threatened to quit the film. Scott only agreed to come out after forcing Schrader to promise that he would never direct again (obviously, Schrader went back on his promise).
- Production Posse: A number of the cast and crew on this pictured had worked on the earlier Paul Schrader scripted Taxi Driver which dealt with some similar themes and settings. This included actor Peter Boyle, editor Tom Rolf, screenwriter Paul Schrader, music editor Shinichi Yamazaki, and cinematographer Michael Chapman.
- What Could Have Been:
- Warren Beatty wanted to play the lead role, but he wanted Paul Schrader to rewrite the script so he would be either the girl's brother or boyfriend and would be searching instead for either his sister or his girlfriend and not his daughter. Steve McQueen also turned it down.
- Schrader originally had Jake discover that his daughter has been killed in a totally unrelated car crash, at which point he simply goes back home.
- Real-life adult film actress Marilyn Chambers was Schrader's preferred choice as Niki, but was vetoed by producers.
