According to the 'Virgin Film Guide', John Cassavetes was not allowed by Menahem Golan and Yoram Globus on this film to participate in his alleged usual self-indulgence, with the producers watching over him throughout the production.
In 2012, Japanese film director Shinji Aoyama selected this film as one of his Greatest Films of All Time. Aoyama has said: "When I think about Cassavetes, I always feel happy. I feel glad that I like movies. I'm sure I will always feel this way until the day I die, and I intend to feel this way too. At the end of Love Streams (1984), Cassavetes smiles as he sees the dog next to him, which turned into a naked man. I live my life always wishing I can smile like that".
Jon Voight originated the role of Robert Harmon in the stage play and was originally slated to reprise his role in the film, but left the production due to scheduling conflicts and "creative differences" with John Cassavetes.

The film was originally released with a running time of 141 minutes which then got cut back to around two hours. When released on videotape in the USA by MGM/UA, the running time was 122 minutes ("one scene was edited and several unusual visual effects (the insertion of black leader and jump cuts) were removed"). Some 1980s home-video tapes, such as the Australian release, though still had distributed the two hours and twenty minute version. The French DVD release has the film still run at its entirety at 135 minutes (PAL TV, this is the same as 141 minutes in theaters), its only current [to date, August 2013] DVD release, on a double bill with Cassavete's A Child Is Waiting (1963).
Final film as a cinematographer for Al Ruban who also acted in the film, something he had done once before, as a regular collaborator in various capacities with John Cassavetes, but more often than not, Ruban produced a Cassavetes written and directed independent film, but was not a producer on this John Cassavetes film.
Wikipedia states that, according to Boston University film scholar Ray Carney, lead actress Gena Rowlands "became involved in the screenings of [John Cassavetes'] Husbands (1970) and Love Streams (1984)", after Rowlands had attempted to allegedly suppress an early version of Cassavete's first film Shadows (1959).
