Now that we pretty much know that the final book in the Twilight saga, Breaking Dawn, is being broken into two movies (it's not been confirmed, but there are few who don't expect it to happen), arguably the big question remaining is just who Summit Entertainment is going to rope in to direct them.

It's easy enough to rule out Catherine Hardwicke, who helmed the first movie, as she's now looking to do The Girl With The Red Riding Hood with Amanda Seyfried (also, it does seem that she and Summit aren't best of chums). David Slade, who's putting the finishing touches to Twilight: Eclipse, is not someone Summit appears keen to re-recruit either.

Yet, Chris Weitz, the man who steered the ship on Twilight: New Moon, has been near the top of most people's list to at least take on one of the Breaking Dawn movies. However, that idea now appears dead, as the director himself has ruled himself out of the running.

"Of course I'm interested," he told MTV. "But I think I'm on record saying I have a 2-and-a-half-year-old son."

"Because it'd be such a long shoot for 'Breaking Dawn', it kind of brings me to the edge of my physical and mental endurance. And I just don't believe I have it in me, and I think that it's appropriate that someone else go ahead and do it."

Summit's search, therefore, continues. We'd like it to take the kind of gambles that Warner Bros eventually started taking with its Harry Potter movies, ideally, but given how crucial the Twilight saga is to the fabric of Summit Entertainment, don't be surprised if it goes for a safe choice.

We wonder what Mr Ratner is doing?
