Bill Marsilii (Deja Vu) came up with the original concept which is currently under wraps. All The Hollywood Reporter was able to dig up was that it will be a dark thriller with supernatural elements. Could it have some ghostly themes? Spirits often do seem to be portrayed as lowering the ambient temperature in a room.
Witherspoon and Pacific Standard Films partner Bruna Papandrea (Gone Girl) brought the project to Lionsgate, which, known for its genre movies, jumped at the chance to start developing it. And while not all of Witherspoon's produced movies have been hits (fugitive comedy Hot Pursuit struggled at the box office), she has helped bring the likes of Wild (2014) and Gone Girl (Gone Girl) to the screen. The actress has a number of movies in the works, including Ashley's War, All Is Not Forgotten, Pale Blue Dot and a live action take on Peter Pan character Tinkerbell in Think.
