Dimension Films said it will release the supernatural thriller Demonic on December 12. Maria Bello and Frank Grillo star in the pic based on an original idea by Saw and Insidious co-creator James Wan, who’s becoming a go-to guy in the genre and most recently directed Fast & Furious 7 for Universal. Wan and Lee Clay are producing and Will Canon directed. Pic centers on the aftermath of a massacre where five college students/amateur ghost-hunters were murdered inside an abandoned home and a pair of detectives try to figure out what went down.
