Throughout the movie, no one's name is mentioned.

There is no musical score for the film.

Jennifer Lawrence is barefoot for the entire movie.

The following statement by Darren Aronofsky was released a week before the premiere: "It is a mad time to be alive. As the world population nears 8 billion we face issues too serious to fathom: ecosystems collapse as we witness extinction at an unprecedented rate; migrant crises disrupt governments; a seemingly schizophrenic US helps broker a landmark climate treaty and months later withdraws; ancient tribal disputes and beliefs continue to drive war and division; the largest iceberg ever recorded breaks off an Antarctic ice shelf and drifts out to sea. At the same time we face issues too ridiculous to comprehend: in South America, tourists twice kill rare baby dolphins that washed ashore, suffocating them in a frenzy of selfies; politics resembles sporting events; people still starve to death while others can order any meat they desire. As a species our footprint is perilously unsustainable yet we live in a state of denial about the outlook for our planet and our place on it. From this primordial soup of angst and helplessness, I woke up one morning and this movie poured out of me like a fever dream. All of my previous films gestated with me for many years but I wrote the first draft of Mother! (2017) in 5 days. Within a year we were rolling cameras. And now two years later, it is an honor to return to the Lido for the world premiere. I imagine people may ask why the film has such a dark vision. Hubert Selby Jr., the author of Requiem for a Dream (2000), taught me that through staring into the darkest parts of ourselves is where we find the light. "Mother!" begins as a chamber story about a marriage. At the center is a woman who is asked to give and give and give until she can give nothing more. Eventually, the chamber story can't contain the pressure boiling inside. It becomes something else which is hard to explain or describe. I can't fully pinpoint where this film all came from. Some came from the headlines we face every second of every day, some came from the endless buzzing of notifications on our smartphones, some came from living through the blackout of Hurricane Sandy in downtown Manhattan, some came from my heart, some from my gut. Collectively it's a recipe I won't ever be able to reproduce, but I do know this serving is best drunk as a single dose in a shot glass. Knock it back. Salute!" [Aug. 2017]

First film by Darren Aronofsky not to feature Mark Morgolis. The pair have collaborated on every on of the director's films since his debut with Pi (1998).

Actors Brian Gleeson and Domhnall Gleeson, who play the two brothers in the movie, are brothers in real life.

Michelle Pfeiffer admitted not understanding the script the first time she read it, describing it as "esoteric." However, the actress committed to the project after becoming excited by the character she would be playing.

Jennifer Lawrence and Darren Aronofsky started dating during the production of this film.

Jennifer Lawrence got so much into her character that during the climactic scenes, she started hyperventilating and even cracked a rib.

The film received both boos and a standing ovation during its premiere at the Venice Film Festival.

Paramount canceled the upcoming Friday the 13th film in order to move ahead with this film.

Jennifer Lawrence helped come up with the idea of her character going barefoot throughout the film to emphasize her character's connection to the house.

Jennifer Lawrence dropped out of The Rosie Project (2019) in order to work with Darren Aronofsky on this movie.

Darren Aronofsky said the exclamation point in the title is a reference to the last 30 minutes of the film.

Originally titled Day 6.

Received an "F" CinemaScore, the worst possible score, which is very rare: Only 19 features have ever received an "F". [Sept. 2017]

Darren Aronofsky wrote the first draft of the script in just five days.

The Mother! poster is a replica of the Rosemary's Baby (1968) poster (horror directed by Roman Polanski).

The film was shot using 16 mm film. This is the fourth time Darren Aronofsky has shot a film on this format.

After filming the scene in which Jennifer Lawrence hyperventilated and cracked a rib (and production was put on hold while she was placed on oxygen), members of the crew came up with the idea to make Lawrence her very own "happy place," a small room to keep her relaxed and steady during filming. It was a tent complete with scented candles, gumballs, and a TV with clips of "Keeping Up with the Kardashians" that play on a constant loop.

There is a 21 year age gap between Javier Bardem and Jennifer Lawrence, who play a married couple in this film.

Jennifer Lawrence met with Darren Aronofsky to hear his ideas before there was a script. After she read the script, she said she was so shaken by it that she threw it across the room.

According to writer/director Darren Aronofsky his inspirations for the film included Luis Buñuel's The Exterminating Angel (1962) and Susan Griffin's 1978 book "Women and Nature".

The film cast includes two Oscar winners: Javier Bardem and Jennifer Lawrence; and three Oscar nominees: Ed Harris, Kristen Wiig and Michelle Pfeiffer.

The movie's marketing team came under a good amount of fire after they hired an artist to paint a mural of the film in Sydney, Australia. Apparently, the mural covered up a 20-year-old painting by a local artist depicting animals in a cityscape below the words "it's like a jungle sometimes." This line refers to a song by Grandmaster Flash and The Furious Five. Darren Aronofsky was embarrassed about the mural being painted over the historic piece of art and apologized on behalf of the ad agency, Apparition Media. A spokesperson for the agency said they were unaware of the iconic nature of the mural and regretted their "terrible mistake." The agency has since contacted the mural's original artist and offered their help in restoring the artwork to its original form.

Edinburgh educated sculptor Jessica Harrison is the artist whose works are referenced in the film's poster image released on Mothers Day 2017. Aronofsky cited Harrison as an inspiration, especially her 'broken' figurines works.

Jóhann Jóhannsson wrote the original score for this movie before it was replaced, according to IndieWire.

The release date was originally set for October 13, but it was pushed forward to September 15.

With a US box office of only $7.5m on the first weekend, this was Jennifer Lawrence's worst wide release opening ever. [2017]

Jennifer Lawrence described Michelle Pfeiffer's work in the film as her best performance and revealed that she forgot her lines during one scene when Pfeiffer was walking towards her because she was so taken with the color of her eyes.

Jennifer Lawrence says "excuse me" about 7 times in the film.

In the film, there are 11 scenes that are strikingly similar to 11 scenes from the thriller House of Good and Evil (2013)

Prior to the start of principal photography the cast rehearsed for three months in a warehouse during which time Aronofsky was able to "get a sense of movement and camera movement, and learn from that".

Darren Aronofsky submitted a written statement about the film when it premiered at the Venice Film Festival, in which he revealed that he wrote the first draft of the script in 5 days ("a fever dream," he called it) and that the idea was inspired by current events, "the endless buzzing of notifications on our smartphones," and his experiences going through Hurricane Sandy in downtown Manhattan. "It is a mad time to be alive," he wrote. He also wrote that the film should be "drunk as a single dose in a shot glass. Knock it back."

Jennifer Lawrence and Andreas Apergis have both appeared in X-Men Days of Future Past.

In keeping with the biblical allegory of the film, the guests begin mocking Mother Nature by bouncing on the sink that she has told them not to sit on. This leads to the house flooding and all of the guests being gone, a reference to the great flood in the Bible wiping out most of humanity.

During an interview with Indiewire, Aronofsky explained the concept of the movie: "Lawrence is Gaia, or Mother Earth, while her house represents the world -- a living, breathing organism being destroyed by its inhabitants. Her husband, known as 'Him' in the film, is God. Out of boredom, he creates Adam and Eve (the couple), who proceed to destroy both Gaia's creation and His study (the Garden of Eden), which holds God's perfect crystal (the apple). Their quarrelling sons are Cain and Abel. They also bring worshipers to praise God, who keep sitting on mother's unsupported sink, and eventually, cause the pipes to burst into a 'Great Flood'. God impregnates mother, who gives birth to the Messiah -- a chaotic sequence followed by a disquieting communion and Revelations."

When the husband is holding the doctor over the toilet, mother notices him covering a wound on the doctor's chest. Going with the biblical theme of the movie this is probably the rib God took from Adam. The next day the doctors wife (Eve) arrives at the house.

Jennifer Lawrence appears in every scene of the film, except of the opening and the closing scenes.

The graphic death of the newborn baby in the ending led to difficulties in finding a distributor for the film. 20th Century Fox turned away the script (after having worked with Aronofsky for quite a few films) along with several other studios, because of this scene. Paramount pictures was only convinced to pick up the film after seeing who would be cast as the characters.

Despite top billing as part of the cast, Kristen Wiig only has about 5 minutes of screentime.

In a Q&A after the film at the Landmark in Los Angeles on September 16, 2017, Aronofsky confirmed that the title "mother!" refers to Mother Nature, whom Lawrence portrays, and that the main characters are based on biblical characters. Bardem is billed as "Him," the only credit with a capital letter; he's God. Harris is Adam, Pfeiffer is Eve, and their sons are Cain and Abel.

The opening shot being repeated toward the end is heavily influenced by the film Crimson Peak (2015).

Him (Javier Bardem) has a capital "H" in his credited character name and, near the end, says, "I am I," which is a line God uses in scripture.

The films beginning is a reflection of the end. Jennifer Lawrence's character wakes up after the opening shot of the burning corpse, at the end of the film Lawrence's character is burned and the next shot shows another woman waking up

The film is a telling of mother nature, hence the title mother! And also explains the lack of names for characters other than descriptive epithets. The house represents Earth, with Jennifer Lawrence representing Mother nature. Javier Bardem's character apprently represents God according to Arronofsky. Michelle Pfeiffer and Ed Harris are adam and eve. With the Gleeson brothers being Cain and Abel. The metaphors continue on throughout the film.

During the riots that happen in the house, some of the chants were actual chants from Egypt in the Egyptian revolution.

An unconventional role for Kristen Wiig, this film along with All Good Things (2010) are her only serious and dark film roles in contrast to her filmography which mostly contains comedy films and other lighthearted roles. This film is also her first horror film and it features her first onscreen death scene, where her character is killed by an explosion.
