The hot topic of Hollywood is anime. We all know that Speed Racer is about to hit theatres but that is just the first of many. Akira is being produced and stared in by Leonardo Dicaprio, Ghost in the Shell is being done by Steven Spielberg, and Avatar The Last Air Bender by M. Night Shyamalan.

I think Akira is going to be hard to create a live action of. Those that have seen it know what I'm talking about. It might take away from the overall production.
Never been a fan of Ghost in the Shell so can't comment on it much but hopfully Spielberg doesn't make the same mistakes he did in AI.
Shyamaln doesn't seem like the guy for Avatar. He is also hit or miss with his movies, so lets hope he hits this time.
