''The Devil Inside'' is a 2012 FoundFootage {{Horror}} film focusing on a supposed exorcism and the aftermath thereof. Costing $1 million to produce and approximately $10 million to promote, the film made over $35 million in its first week and over $100 million worldwide overall, making it a commercial success despite panning by the critics. Notably, though, its [[NoEnding lack of anything resembling an ending]] caused some audience to [[http://www.youtube.com/watch?v=JAgkNBd78J8 break out in jeers]].

Not to be confused with [[VideoGame/TheDevilInside the survival horror game of the same name]].

Visit therossifiles.com for more information on the ongoing investigation.''' The website had ''virtually zero'' tie-in material to the film, mostly limited to standard promotional material like character bios and ticket information.
