- Acclaimed Flop: Got alright reviews for the most part, but audiences were turned off by the movie where it only grossed $17.8 million in the domestic box office.
- All-Star Cast: Jennifer Lawrence, Javier Bardem, Ed Harris, Michelle Pfeiffer, Domhnall Gleeson and Kristen Wiig.
- Big Name Fan: Martin Scorsese personally went to bat for the film, defending the film from critics, Cinemascore, and Rotten Tomatoes. As Scorsese noted, the "F" Score from Cinemascore is a distinction that mother! shared with movies by Robert Altman and Steven Soderbergh.
- Box Office Bomb: Budget, $30 million. Box office, $17,800,004 (domestic), $44,400,272 (worldwide). While it broke even thanks to the worldwide gross, it only grossed approximately $7.5 million domestically on its opening weekend.
- Creator Backlash: Not towards the movie, but if her comments gave any indication, Jennifer Lawrence thinks the baby death was pushing it too far.
- Creator Breakdown: According to Jennifer Lawrence in an interview shortly before her breakup with Darren Aronofsky, Aronofsky suffered this after the film was released. It would apparently be all he talked about, even when Lawrence asked him to move on from the subject and he began exhibiting Can't Take Criticism and Dear Negative Reader which, along with the age difference, led to their breakup. Doubles as Tear Jerker.
- Doing It for the Art: Darren Aronofsky was initially skeptical as big a star as Jennifer Lawrence would sign up for a project as grueling and potentially audience-alienating as this one, but it turned out she was a big admirer of his films and jumped at the chance to work with him. So much so that they started dating while working on this film.
- Dueling Works: With It (2017), for a September horror release. It easily won, with it being one of the highest grossing horror movies of all time; while this could be a cult classic at best.
- Playing Against Type: Kristen Wiig, whose role is certainly not the comic type for which she is most known. She plays Him's publisher, who appreciates Him's art and Mother's inspiration one moment and shoots a group of hostages with bags over their heads point blank the next.
- Production Posse: As usual, Darren Aronofosky would still have Matthew Libatique as his cinematographer and Andrew Weisblum as his visual effects editor. However, this is the first Aronofsky film to not include music by Clint Mansell or a supporting performance by Mark Margolis.
- Real-Life Relative:
- Brothers Brian and Domhnall Gleeson played as actual brothers in the movie.
- Darren Aronofsky's real-life father, Abraham, played as a "wanderer" who walks into the bathroom where "mother" is changing her clothes.
- Reality Subtext: Jennifer Lawrence plays a young woman in a doomed MayDecember Romance. During filming, Lawrence began dating director Aronofsky, but they broke up a year later, with their 22-year age difference being cited as a major cause.
- Relationship Voice Actor:
- A cross-language version between the Latin American Spanish and Japanese dubs: The voice actresses of the titular mother (Carla Castañeda and Miyuki Sawashiro respectively) both voiced Twilight Sparkle in the respective languages.
- In the Latin American Spanish dub, the mother and Him's voice actors (Carla Castañeda and Juan Carlos Tinoco respectively) are both Symmetra and Doomfist respectively.
- Romance on the Set: Director Darren Aronofsky and Jennifer Lawrence dated on the set of this movie.
- Screwed by the Network: Instead of releasing the film in August 2017, which was such a dry month for movie releases that even the notoriously badly-reviewed The Emoji Movie was able to turn a significant profit, Paramount released it the following month... one week after the massively successful opening of It (2017). While this was likely just incredibly bad luck on Paramount's part, as the success of It caught nearly everybody off-guard, it'll likely be of scant consolation.
- Shrug of God: Darren Aronofsky has, unsurprisingly, kept mum about any "correct" interpretation of the film's allegory, responding to an interview question about it with the classic "This space intentionally left blank."
- What Could Have Been: Ironically, Aronofsky claims his original intentions with this film were to get away from Surreal Horror back to a traditional horror concept of "a home invasion movie" only to get caught up in the metaphorical possibilities of the deeper meaning of "nightmare guests who won't leave".
- Word of Saint Paul:
- Interviews with cast and crew, most notably Jennifer Lawrence, give the impression the primary intended meaning of the film was an allegory about climate change and humanity's disrespect for the Earth in general.
- Javier Bardem addressed the Reality Subtext of people seeing Him as Aronofsky's Author Avatar, claiming Aronofsky is "the opposite of my character" and that his treatment of Lawrence on set was the opposite of Him's treatment of mother.
- Working Title: Day Six, a reference to God creating Adam and Eve on the sixth day of creation in Genesis, giving them both "dominion over the Earth" and the responsibility to "replenish" it.
