joker could turn to crane because he has heard of his altercations with the batman.
"you work for me now!'
I just love the idea of Scarecrow and Joker having scenes together in any way, shape or form.
then again could this not be the vigilante batman? crane puts him in the back of the van, and delivers him to the joker?
all guess work.
I'm really liking the sound of this.
Perhaps, rather than a simple Joker/Scarecrow team-up, "The Dark Knight" is going to be about gang war? Joker's gang, Maroni's gang, Scarecrow's gang, the European mobsters, some group that connects to Hong Kong. All battling each other for territory. It could be like, Falcone's gone, so everyone wants their piece of the Gotham pie.

Is there any confirmation, that this scarecrow is indeed murphy?
It could be anybody underneath that mask...
Its him I saw him in person
was he wearing just a suit? a nice suit or an actual 'scarecrow' outfit..(like it matters..haha...I'm not nitpicking)
