I’ve never been into Disney flicks and I haven’t heard anything about this one. Either cuz it’s way out there in 2014 or the Mickey Mouse guys are having second thoughts about a ‘Finding Nemo’ with ghosts. Might be passable if it’s like Sixth Sense. I’ll wait until more info comes out before reserving any tickets though 
The book is really good. Not sure if Disney should be doing it though.
