Barbra Streisand was paid $4 million dollars for her performance in this film, which made her the highest paid actress in Hollywood at the time. Streisand also apparently had points totaling 15% of box-office returns.

The UltraSave All-Night Drug Store seen in this picture was so realistic that people went in and tried to shop there. It was explained to them that it was a movie set but one woman exclaimed, "But we NEED a drug store in this area!"

Actor Kevin Dobson once said about being cast as Barbra Streisand's husband in this movie: "I'd once worked thirteen days as an extra in Funny Girl (1968). I knew I'd work with her eventually. She's wonderful to work with. We rehearsed our parts. I've had such rapport with her. She has a reputation, but I never saw anything but the utmost professionalism."

Actress Lisa Eichhorn once said on her being replaced by Barbra Streisand: ""I could understand being replaced by Amy Irving or Sissy Spacek. Or someone else of my own age and nature. But Barbra Streisand? I thought All Night Long (1981) was some of my best work."

Gene Hackman once said on the casting of Barbra Streisand and the script's re-writing because of this: "The way the part was written, it wasn't that big and would be a waste of her time and talents."

Gene Hackman once commented to newspaper columnist Marilyn Beck about Lisa Eichhorn's replacing: "She's got enough problems, and I've been fired myself. I know how it hurts."

This film's stills photographer Greg Gorman once told Roald Rynning what it was like to work with Barbra Streisand: "Before photographing Barbra the first time, I was a little nervous. I'd heard she was demanding. I was hired only to take stills from [All Night Long (1981)], but I asked to do a special shoot with her. I remember her office called me, asking what other big female stars I had shot. I had to answer I had done none. Nevertheless, one day on the set, Barbra came over. 'I hear you want to take some pictures of me', she said. 'What did you have in mind? What colors do you want to use?' I answered her straight back. Asked her what colors she liked and the interrogation was over. From then on she was terrific. For a photographer it's easy to work with her. She knows her face very well, the angles, the lot. She loves to see my Polaroids and analyze the results. I think a great deal of her success has come from asking questions and being a terrific observer."

Lisa Eichhorn was originally cast as Cheryl, but was replaced by Barbra Streisand during production. Eichorn had worked a whole week before she was replaced. Streisand was suggested for the role by her then agent Sue Mengers who was in a relationship with this movie's director, Jean-Claude Tramont.

This movie was originally conceived as a comeback movie for Gene Hackman. By the time the film was made, he had already "comeback", being seen in a cameo as Lex Luthor again in Superman II (1980). Hackman took a two year break from filming around 1978 stating that he was exhausted having made fourteen movies in a row after The French Connection (1971).

It has been alleged that because this movie bombed at the box-office, Barbra Streisand sacked Sue Mengers, her agent.

Reportedly, Gene Hackman and Lisa Eichhorn did not get along during the first week of filming on this picture and this lead to Eichorn being replaced.

Barbra Streisand has since stated that she doesn't like the film. She also mentioned that, in order to research for the film, she went out once or twice in disguise.

This movie's working title was 'Night People'.

Barbra Streisand was able to do this picture as her pet project Yentl (1983) was taking longer in development than originally foreseen and Streisand had not appeared in a movie for two years, her last picture being The Main Event (1979).

The UltraSave All-Night Drug Store featured in this movie cost three-quarters of a million dollars to stock from one hundred and thirty different companies.

Barbra Streisand sings only intermittently in this movie and only as part of one comic interlude where she attempts to compose a country 'n' western song on a musical organ at her house.

This movie's screenplay was re-written for Barbra Streisand when she came on board for the picture.

This is the only Barbra Streisand movie, besides Meet the Fockers (2004) in which Streisand is not the central character.

Agent Sue Mengers' once said of the post-movie break-up with client Barbra Streisand: This picture ". . . caused a lot of strain between Barbra [Streisand] and Jon [Peters]. Because it was the first thing Barbra had done where Jon wasn't involved. He liked to get producer credit. And this one announced to the industry [that] she's a free agent. Producers didn't feel, 'Omigod, if I bring that script to Streisand, I'll have to bring in Jon Peters.'"

This picture's director Jean-Claude Tramont once spoke of the fact that his wife Sue Mengers was Barbra Streisand's agent at the time. He commented on the media circus' response that ensued which suggested that Mengers heavily persuaded Streisand to do the picture as a personal favor to her: "My wife and I have been together eleven years. If she had the ability to force Barbra to do a picture with me, I wish she had used it sooner. In most of her pictures, she [Streisand]'s criticized for overpowering the screen. In All Night Long (1981), she's criticized for not overpowering the screen." Tramont stated that Streisand took the part because she wanted to play a different type of character to what she had done before.

When Barbra Streisand replaced Lisa Eichhorn on this picture, Gene Hackman heard that Streisand would be getting paid US $ 4 million. Apparently, Hackman refused to go to the set until his salary for this picture was adjusted accordingly.

After this picture was made and released, reportedly in late 1981, Gene Hackman did not like to talk about this picture nor his co-star Barbra Streisand.

Terry Kiser (Ultra-Sav Day Manager) and Hamilton Camp (Buggoms) both later played H.G. Wells in Lois & Clark: The New Adventures of Superman (1993): Kiser in Lois & Clark: The New Adventures of Superman: Tempus Fugitive (1995) and Lois & Clark: The New Adventures of Superman: Soul Mates (1996) and Camp in Lois & Clark: The New Adventures of Superman: Tempus, Anyone? (1996) and Lois & Clark: The New Adventures of Superman: Lois and Clarks (1997).

Barbra Streisand received second billing to Gene Hackman for this movie.

One of the main movie posters for this picture has Barbra Streisand climbing on a pole wearing a large dress with three male characters beneath her, evoking a classic movie scene from The Seven Year Itch (1955) where Marilyn Monroe's dress flies up in the air from a breeze blown from a street subway grill.

American movie debut of French director Jean-Claude Tramont. Tramont previously had only directed one movie, a French film entitled 'Focal Point' [See: Focal Point (1977)].

This movie was mostly shot on location with only two days filming on studio sound-stages.

Sue Mengers, the Hollywood agent of Barbra Streisand and Gene Hackman at the time this picture was developed and made, was married to this film's director, Jean-Claude Tramont.

The UltraSave All-Night Drug Store scenes were filmed at a then empty Pasadena supermarket which was re-stocked with merchandise for this picture.

This is the only ever theatrically released American movie of French director Jean-Claude Tramont.

Prior to this American movie, the only American movie experience this film's director Jean-Claude Tramont had was writing the screenplay for Ash Wednesday (1973).

This movie's director Jean-Claude Tramont once commented on the casting of Gene Hackman: "He'd been doing these harsh roles. But he was so funny in that five-minute sequence in ;Mel Brooks''s Young Frankenstein (1974), where he played a blind, somewhat fey, monk, I always wondered why nobody used him in comedy."

This film's director Jean-Claude Tramont once said of Lisa Eichhorn's replacing: Eichorn was let go because ". . . the part was too much of a stretch for Lisa. It's no reflection on her acting ability."

Production shooting of this movie was shut-down for one week between Lisa Eichhorn being fired and replaced by Barbra Streisand.

Loni Anderson was considered for Cheryl Gibbons.

This 1981 released movie was first announced in 1978.
