No, they are too busy fighting all their legal battles with their own staff. Mickey abuse will just be free advertising.
That was my read on the 'Winnie the Pooh' horror flick. The only motive for doing it would be the free media coverage.
IMO that's kind of playing with fire. You've pissed off Disney and drawn their attention. They have the power to make some phone calls and dictate what the entire MSM says about your movie. If your movie had some quality then you might end up regretting that.
But if the movie is total cheap garbage then you have nothing to lose. Then it might be wortwhile to pull a Winnie/Mickey IP stunt.
