John Carter of Mars (2012)
I remember reading many of ERBs books when I was young and thought it was a great adventure.
For those of you who are waiting for the real deal... see whats coming in 2012.
Let me just say... Dirctor = Andrew Stanton
I doubt it will be exactly the same the books I remember, but based purely on the Dicector, I imagine it will be BETTER in so many ways.
PS see his list of credits, both as director, writer and producer.
