Havent heard anything about this yet, but even tho I wish they would do FAC for this one as I love the film so much, I think they should finish the ones they already started.
I can only imagine if adding this one to the FAC line up we wouldnt see it in the first quarter of 2016.
I have seen FA discussing their plans for The Walk and The Martian, but you never know they might suprise us like they did with the MI5. Wouldnt mind seeing Scorch Trials to match with their first Maze Runner FAC.
