The movie had several failed theatrical release dates including January 27, 2012; January 3, 2014; January 2, 2015; April 15, 2016; April 1, 2016; January 6, 2017 and June 30, 2017. The film was finally given a limited theatrical release on October 28, 2017 before the eventual Blu-ray and DVD release on November 14.

The original plan for this reboot was "Amityville: The Lost Tapes." Written by Casey La Scala and Daniel Farrands and utilizing the found footage angle, the plot involved "an ambitious female television news intern, on the verge of breaking the most famous haunted house case in the world, who leads a team of journalists, clergymen and paranormal researchers into an investigation of the bizarre events that will come to be known as The Amityville Horror, only to unwittingly open a door to the unreal that she may never be able to close." After a couple of delays, this concept was eventually scrapped.

The film's tongue-in-cheek advertising campaign features posters which are made up to resemble the social media site, Instagram, with the main character depicted using the site and posting a photo of the infamous Amityville house with the caption: "Moving in today #NewBeginnings".

With a release date of 2017, this was the first theatrically released Amityville film since The Amityville Horror (2005) remake 12 years prior.

This movie was originally rated R but after it was re-edited and sent back to the MPAA, they gave it a PG-13.

The first theatrically released Amityville film to be a completely original story as The Amityville Horror (1979) and its remake were based on a book chronicling the story of the Lutz family while Amityville II: The Possession (1982) was based on a book as well that recounts the story of the DeFeo family (renamed Montelli for the film) while Amityville 3-D (1983) recounts the investigation by paranormal researcher Stephen Kaplan (renamed John Baxter for the film).

Mckenna Grace and Jennifer Morrison have worked together before but not directly. Jennifer Morrison played Emma Swan on Once Upon a Time (2011), while McKenna Grace played one of the younger versions of Emma Swan.

The film was originally titled Amityville: The Reawakening before being renamed Amityville: The Awakening.

13 minutes of footage was edited out of the original 100 minute R rated cut to achieve a PG-13 rating for the 87 minute theatrical cut.

Bella Thorne and Cameron Monaghan have both worked with Adam Sandler. Thorne played his daughter in Blended (2014) and Monaghan in Click (2006).

Had this film not been delayed several times, it would have been the feature film debut of Mckenna Grace.

Is not a true sequel to the Amityville films but is instead a meta film, where this film takes place in the "real world" and the original 1979 film, its prequel, and the 2005 remake are all fictional.

Jennifer Jason Leigh and Kurtwood Smith have both worked with Paul Verhoeven before. Kurtwood Smith on Robocop (1987) and Jennifer Jason Leigh on Flesh + Blood (1985).

Although their characters are supposed to be fraternal twins, Bella Thorne and Cameron Monaghan are actually 4 years apart.

Cameron Monaghan does not speak his first line until 42 minutes into the film.
