It is a remake of the 2014 Austrian film with the same name, and stars Naomi Watts, Cameron and Nicholas Crovetti, Crystal Lucas-Perry, Jeremy Bobb, and Peter Hermann.

When they return home to live with their estranged mother, a former actress, they are disturbed to find that her entire head is covered in bandages after having cosmetic surgery.

The boys are unsettled by their mother's behavior and apparent disinterest in reconnecting with them; she drinks heavily, has a short temper, and refuses to sing them the lullaby she sang to them when they were children.

Their mother, who has now removed her bandage, insists they are imagining things and tells the police that the injury on Elias' lip is from accidentally slipping and falling by the pool.

While they are waiting for a taxi, Elias pretends he forgot his toothbrush and returns to the house, where he searches his mother's purse and finds the contacts.

In April 2021, Variety announced that Playtime had purchased the rights for a remake to the 2014 Austrian film, Goodnight Mommy, which was being developed with Amazon Studios and Animal Kingdom, with Matt Sobel directing, Kyle Warren writing, and Naomi Watts set to star and executive produce (alongside original writers/directors Veronika Franz and Severin Fiala).

[3] In June that same year, Cameron and Nicholas Crovetti were added to the cast including Jeremy Bobb, Crystal Lucas-Perry, and Peter Hermann.

[10] Benjamin Lee of The Guardian gave the film 2/5 stars, writing: "Without the fine, frightening direction of aunt-nephew duo Veronika Fran and Severin Fiala, we're left with very little, a slick but soulless little movie that should appease neither fans of the original nor newcomers.

"[11] Peter Sobczynski of RogerEbert.com gave the film 1/4 stars, saying that it "replicates the basic story beats of the original but leaves out all of the tension, ambiguity, and nasty invention that made that earlier effort so effective in the first place.

"[14] Paul Byrnes of The Sydney Morning Herald gave the film 3/5 stars, writing: "I can't say it's better or worse than the original.

"[15] Noel Murray of the Los Angeles Times praised Watts's performance, but added that the film "pulls back too much from the violence and torture that made the original such a sublime ordeal.
