Nolan and Emma Praise Ledger as the Joker

Still from the press day of The Prestige, reported by News.com.au , Jonathan Nolan, Emma Thomas and Christopher Nolan were all tight-lipped when asked about TDK. Here's what Jonathan had to say:

"Warner Bros has a squad of ninjas that follow me around if I say anything about Batman"

While his brother Christopher, told that Ledger was actually a fan of Batman Begins and Nolan was surprised that Ledger would be interested for the role of Joker.

His wife, Emma Thomas, also speaks about Ledger:

"He's very much like Christian (Bale), where he commits his body to whatever role he is playing."

So now we all know that we cannot hope anything new about The Dark Knight before the big guys on WB decide to announce it. They don't want it ended up like the Ledger casting did.
