Sinister 2 (stylized in marketing as Sinister II) is a 2015 supernatural horror film directed by Ciarán Foy, and written by Scott Derrickson and C. Robert Cargill. A sequel to Sinister (2012), it stars James Ransone, reprising his role from the original film, and Shannyn Sossamon. The film follows a former deputy as he attempts to put an end to a malevolent deity's curse after an encounter with a family that fell victim to it, while a boy is tormented by the victims who lived in the house where he, his twin brother, and mother now reside. Unlike the first film, which utilized 8 mm film in the story's home movies and snuff films, Sinister 2 utilized 16 mm film, vinyl records, and ham radio broadcasts in the film's storyline.

It grossed over $54 million against its reported budget of $10 million.
