A recent Gossip Monkey on Moviehole told an interesting rumor about whether Katie Holmes going to be back for the sequel. It goes like this:

There’s talk that Katie Holmes won’t be back in the ‘Batman Begins’ sequel. If that’s true, then why – a couple of weeks back – did I see Chris Nolan and Holmes chatting under an umbrellaed-table at Warners?

Well, maybe they just chatting out something else. Their world is not just Batman, isn't it?

“I should be a lot further down the line but I’ve taken time out to do this tonight,” Nolan grins, “but we’re getting along pretty well. We’re moving along from the last story and it’s a pretty logical progression, but it’s going to be exciting."
