This is ridiculous.
People are not giving MJ enough credit. He is a master craftsman. He is genius, he is doing what he does best, what he knows inside out. To say he was insecure and unsure is, in my opinion, BS. If he seems all too humble it's because he is thinking 'ok you're not doing it right, it's gotta be better, but i'm not going to come down hard on you'. It's in his nature.
Michael Jackson has been there, done that, MANY MANY times before. This isn't the first time he was involved in a stage production work scenario. Why would people think things all of a sudden happened in backstage in This Is It and have not happened before.
Give MJ credit. He is the King, he's been at the very top, and to me he looked very chilled and not taking crap from anyone (not that anyonre would give him crap). If he seems uneasy i think it's just because he was frustrated maybe sometimes that people around him were not quite at the level he wanted them to be, or just making mistakes that only he heard.
Besides, the dancers and musicians, and him, looked to have a lot of practise behind them and looked polished - apart from him not giving 100% at times (which is normal).
Also - how many times would such a production need to be run through full dress rehearsals? I wouldn't think it's as many as people assume. Being in London and having 2 weeks, they could've rehearsed with full dress rehearsal the whole show in its entirety every couple of days and it would've been enough..
Kenny even says there were doubts the show, and Michael would be ready, but things were coming together in the 2 days before Michael's...yeah....
This show was going to blow anything before it out the water. Too many experienced people working on it to let it slip.
Enjoy the movie people, focus on the positives - because the negatives even if they may exist are simply commonplace in this industry and are insignificant.
MJ takes no crap, MJ was ready. I love the movie.
