casting heath ledger as joker in the first place would never
have occurred to me. he was too much of a good guy in brokeback
mountain, monsters ball and knight's tale.
my personal favorite to play joker, joaquin phoenix (walk the
line). he's got promise. with some luck, there's probably enough to
surpass ledger's performance.
johnny depp has too much recognition behind him. takes the joy
out of expectations.
I dont think there will be the joker in the sequel. Cos usually
they dont repeat the villian. Thts wad i think.
