Note of caution: Anyone read the godawful script Aaranofsky and Frank Miller turned out for a potential adaptation of Batman: Year One some time ago. Where Alfred was a jive-talking black guy and Batman got his name because of the Bat-shaped indentations left by punches thrown when wearing his father's rings? Where the Batcave was a garage?
Still, for all that, he's a talented director and the combination of his and McQuarrie's abilities ought to make for a good movie. I'd also be perfectly happy if Slade landed the gig, on the basis of his excellent 40 Days of Night.
