An example of what kind of culture Chappie will truly need to change if he wants things done "quicker and cheaper": for the demolition and prep work scheduled for The Corpse of The Disney-MGM Studios (no, fanbois, meeting and rubbing yourself up against an CM pretending to be Kylo Ren isn't a reason to plan a visit!) isn't divided into a few jobs (or contractors) or even five or six.
Hell, no, this is Disney we are talking about. So, last time I checked the number was in the 'hood of 60 separate ones. Think about that.
You just can't do massive projects like this. So good luck to Chappie!
