I thought 9 was a cool film! I was it at the cinema and enjoyed it. Every so often I did notice some weird textures and other bits, but that was just me being picky.
First reaction: Why would they hire 9 directors for one movie? :P Reminds me of Crytek's Sandbox for Cinema. I hope it works well so switching between movie and games industries can become less of a hassle for at least someone.
I met Shane Acker at a conference once (he was the keynote speaker, and socialized with some folks at the after party) and he was a really cool guy. 9 had it's flaws but I liked it. This sounds like an awesome collaboration, I look forward to seeing what comes of it.
