Producer Jason Blum Talks 'Sinister' & The 'Paranormal Activity' Recipe For Success

Jason Blum had produced a dozen projects before he hit upon 2007's sleeper phenomenon Paranormal Activity, a micro-indie horror pic with no stars that in turn became the model for Blumhouse Productions, his own genre-leaning multimedia label. Fast forward just five years and Paranormal Activity 4 is set to continue the series' low-budget thrills (with webcam technology!) next week, while the Blum-produced Sinister, about a writer (Ethan Hawke) contending with a house haunted by insidious forces, opens today.
