Nicolas Cage's screen test didn't impress the studio, and they wanted to get someone else to play Ronny. But Cher insisted that Cage was the one to play that role, and threatened to quit unless he was hired. After a few days, the studio relented.

Director Norman Jewison was fined by the actors' union for not allowing his actors to go to lunch until they perfected the moods of their characters for the climax scene in the kitchen.

Norman Jewison has stated that the climactic kitchen sequence was the most difficult scene that he ever shot in his career. The crew were dismissed and Jewison rehearsed with the cast for some time, using a stage production approach. Only after the actors perfected their timing did he decide where to put the camera.

The opening title sequence was originally played on the score from "La bohème" opera but was changed to the Dean Martin track "That's Amore" because the preview drew negative test audience reaction. Many shifted uncomfortably on their seats, thinking that they had been lured into an art film.

According to casting director Howard Feuer, both Anne Bancroft and Maureen Stapleton had been considered for the role of Cher's mother, but their fees were too expensive for the production budget. Feuer remembered Olympia Dukakis, a character actress known for years to most in casting, she read for director Norman Jewison and he hired her instantly.

Norman Jewison considers this movie his favorite of all the films he has directed.

While filming between takes, Cher motioned to Olympia Dukakis that the movie was going to be a dud. She originally thought that she was giving a bad performance. She went on to win the Oscar and Golden Globe for Best Actress.

The film is included on Roger Ebert's "Great Movies" list.

John Mahoney later revealed that his role in the film got him widespread attention, helping him get cast in the TV series Frasier (1993).

Cher is 18 years older than Nicolas Cage.

The studio heads had Peter Gallagher in mind for the role of Ronny Cammareri, but Cher adamantly wanted Nicolas Cage to play Ronny, as she thought he could play "crazy" more realistically. She shot a screen test with Gallagher, and also one with Cage. After the tests, the studio still wanted Gallagher in the role. However, Cher fought for Cage, insisting that she wouldn't do the movie without him. The studio relented, and Cage was cast. Gallagher would eventually be cast in a similarly themed film, While You Were Sleeping (1995).

The despondent moan that Olympia Dukakis repeats to herself throughout the film is a direct homage to the same moans that Dustin Hoffman delivers throughout "The Graduate".

According to Nicolas Cage, the acting style he was channeling while doing the hand speech was inspired by watching the body language of actor Rudolf Klein-Rogge in director Fritz Lang's 1927 German expressionist film 'Metropolis'.

Olympia Dukakis is only 15 years older than her on-screen daughter Cher.

The film cast includes three Oscar winners: Cher, Olympia Dukakis and Nicolas Cage; and two Oscar nominees: Vincent Gardenia and Danny Aiello.

The opening credits show a sign advertising the opera "La Bohème", conducted by "Roger Paradiso". Roger Paradiso was involved with the production of this film.

Watch the shot where Johnny kneels down in the Grand Ticino - as he kneels down and his face nearly leaves the camera with the nervous expression, you can see him burst out laughing for about one second. If you listen closely, you can hear people laughing at him, obviously the camera crew.

When Johnny hails a cab at the airport after his return from Sicily, he asks the driver to take him to "19 Cranberry Street, Brooklyn." This is a real house located a few blocks from the East River, just like the exteriors shown in the movie.

Screenwriter John Patrick Shanley wrote the film's script with Sally Field in mind for the lead role, which in the end was played by Cher instead.

1987 was a busy year for Cher. Along with Moonstruck, she also starred in the feature films Suspect (1987) (with Liam Neeson and Dennis Quaid) and The Witches of Eastwick (1987) (with Jack Nicholson, Susan Sarandon, and Michelle Pfeiffer). It was also the year she resurrected her solo music career with her hit self-titled album Cher. Sadly, it was the unexpected pinnacle of her acting career. She would only follow up with the box office disappointment Mermaids (1990), eventually disappearing from the big screen altogether. She has only made a few film appearances since in films such as Faithful (1996), Tea with Mussolini (1999), and Burlesque (2010). Though she never regained a big status as an actress, her musical career flourished with hits like "If I Could Turn Back Time" and "Believe". She has stated that acting was too demanding after being diagnosed with Epstein-Barr Syndrome in the late 1980s. Her biggest regrets regarding her acting career include turning down roles in Thelma & Louise (1991), The Addams Family (1991), The Piano (1993), and Death Becomes Her (1992).

The "Old Man" is played by Feodor Chaliapin Jr. (although credited in the film as Feodor Chaliapin). He is the son of Feodor Chaliapin Sr., who was one of the greatest bassists of all time - a Russian who often performed at the Metropolitan Opera in the early 1900s.

The original screenplay featured a subplot that showed the characters played by Cher and Vincent Gardenia volunteering at a men's homeless shelter as penance for their sins. The subplot was discarded.

The storefront (502 Henry St.) that once housed the famous Cammareri Bros. Italian bakery became Maybelle's Cafe for a while. That has since closed and a new restaurant (Purbird Flame Grilled Chicken) opened in 2015. The original bakery equipment is still stored in the basement of the building - it's too big and expensive to remove.

Like several other members of the production crew, costume designer Theoni V. Aldredge is also credited on the poster for "La bohème" shown at the beginning of the film.

That same year, Cher and John Mahoney also appeared in Suspect (1987).
