Amityville: The Awakening is a 2017 American supernatural horror film written and directed by Franck Khalfoun and starring Bella Thorne, Jennifer Jason Leigh, Cameron Monaghan, Mckenna Grace, Thomas Mann, Taylor Spreitler, Jennifer Morrison, and Kurtwood Smith. It is the tenth installment of the Amityville film series and a metafilm taking place in the "real world", where the 1979 original, its sequels, and the 2005 remake are all works of fiction. Its plot follows teenager Belle Walker who moves into 112 Ocean Avenue with her family, who shortly find themselves haunted by a demonic entity using her brain-dead twin brother James' body as a vessel.

Originally titled Amityville: The Lost Tapes, it was announced in May 2011, and was initially conceived as a found footage-style film and a separate entry in the franchise. However, the studio abandoned the film's original idea, and hired Khalfoun to write and direct a new draft in early-2012. Filmed in 2014, the film suffered numerous release delays before finally being released for free on Google Play on October 12, 2017 and on DVD in 2018.

Amityville: The Awakening was theatrically released by Dimension Films in a limited release on October 28, 2017. The film had grossed $8.4 million worldwide and received mixed-to-negative reviews from critics, with criticism for its generic writing, horror clichés and reliance on jump scares. It is the last film to be released by distributor RADiUS-TWC, as the company shut down along with Dimension and their parent company, The Weinstein Company, on July 16, 2018, following the sexual abuse allegations against its co-founder Harvey Weinstein.

Teenager Belle Walker moves to 112 Ocean Avenue in Amityville, Long Island with her mother Joan, younger sister Juliet, brain-dead twin brother James, and dog Larry. The family's reason for moving there was to be closer to Dr. Ken Milton, a neurologist hoping to treat James, who is on life support after an accident that left him paralyzed. Upon moving in, Juliet tells Belle that James has been talking to her lately. That night, James flatlines, but is mysteriously revived and opens his eyes.

At school, Belle is taunted by her peers over moving into the home, which she learns was the site of a mass murder by Ronald DeFeo Jr. in 1974. In her third-floor bedroom, she discovers blood stains from the murder concealed under the wallpaper. One night, Belle invites acquaintances Terrence—an enthusiast on the Amityville haunting—and Marissa over to watch The Amityville Horror (1979) at the house. At 3:15 am in the middle of the film, the power goes out and the three go into the basement to locate the fuse box, where they are confronted by Joan, who thinks they are intruders.

Dr. Milton, who suspects James may have locked-in syndrome, performs an EEG test on James that shows increased neurological function. During the test, Dr. Milton witnesses an apparition of flies filling the room and attacking him, and leaves the house, shaken. James quickly gains the ability to communicate with the family via an AAC computer system that allows him to type by looking at letters on a screen. Terrence suggests to Belle that James' sudden revival may be a result of possession stemming from the house, and they suspect that a ring on the ground surrounding the house may represent a magic circle. Belle explains her troubled past to Marissa and reveals that James sustained his injuries after falling off a three-story balcony during a fight with a boy who had leaked nude pictures of Belle online. Belle asks James if someone else is inhabiting his body, to which he replies "Yes" and "Help" via his computer. He asks her to kill him, and she shuts off his ventilation machine. Joan enters the room and finds that James is now breathing on his own.

The next day, Belle types “Outside walk” on James’ computer in order to distract her mother and find the Red Room in the basement, which she believes to be the source of James’ power. Larry the dog is found mauled to death in the lake by Juliet, and Belle confronts her mother with the theory that the house is possessing James. Joan reveals to her that after having lost her faith in God following the death of her husband and James’ subsequent accident, she moved the family to the home, hoping to harness the demonic energy there in order to bring James back to life.

That night, as Belle prepares to leave, Joan knocks her unconscious. Belle awakens at 3:15 am, just as her aunt Candice arrives at the house. James rises from his bed, and harnesses the energy from the Red Room, which revitalizes his body. Belle makes her way downstairs as Candice enters the house, but James shoots Candice with a shotgun. Belle retrieves Juliet from her room, but the house locks the doors, preventing them from escaping. Joan is confronted by James in her bedroom and knowing she is facing death, she retrieves her crucifix, and holds it toward James, but he is unaffected. He reminds her that with the loss of her faith, God is not able to save her. James shoots Joan in the chest before throwing her on her bed and shooting her in the head. He lures Juliet to the third floor, where he attempts to kill her, but is stopped by Belle, who tackles him, resulting in them both falling from the window. Belle lands on top of James which incapacitates him. She drags James outside the circle, after which his body withers back to its paralyzed form, and he dies after thanking her for freeing him from the possession.
