There definitely is at least one double & I'm pretty sure that orange pants guy is. Not just because of the way he moves (which is weird) but because he seems proportioned differently (shorter legs, longer torso) & it's not just because of his jacket. The real Michael in blue & red's shirt goes just below his hips, same as orange pant's jacket so th jacket's not making his legs look shorter, they just are. Also, he wasn't wearing sunglasses when he was in red & blue & a couple other shots, but orange guy ALWAYS wore them & the Michael in some other shots, they never came off, not once. It's AEG & Sony behind this movie, they are being said to be bad, so why would there ever be any question to them using doubles to cash in? Also if you look on the back of your dvd at the pictures, there's a picture where MJ is holding the mic & smiling, his smile looks really, really wide for his face & if you compare the hand in that picture to the hand in the picture above it, they look different. One looks really young & perfect, the other one looks older & rougher...
