Another Interview with Heath Ledger on his Joker role is posted in MTV. Basically, it's just the same with his previous interviews, that he will not portray Joker the same way that Jack Nicholson or Cesar Romero did. Here's what he said about his preparations for the role:

"I'm refusing to think about it yet," he insisted. "I'm just happy at home and I haven't given it too much thought."

Then, grinning like Jack Napier himself, Ledger did make one evil-sounding statement: "I've got something up my Sleeve," he promised. ...

Meanwhile, Batman-On-Film posted a news about TDK set on Cardington Hangers is getting busy. Here's the report:

“Hi there, just thought I would send you a short email to give you some info that the Cardington Hangers…are getting very busy with lorries and sets in and out all day. A helicopter came in yesterday with Nolan and they all went in to the hanger to check the set out. I have seen the set and it looks good. I think it’s the Batcave they have built this time, but I’ll have to get closer to be sure.

I was lucky to get in the last film and I was on set 8 times. I have included a pic of the hanger and as you can see, it’s getting busy. But today its just gone to overdrive!”
