The other big question mark (aside from how you adapt the predominately darker Breaking Dawn into a film that will appeal to the tween and teen set) is who will direct. David Slade is currently helming Eclipse, the third installment in the Twilight franchise, and from the sound of things that's the only segment he'll be directing. Right now it looks like Summit wants Chris Weitz to finish out the series, which is why -- according to Variety -- they haven't yet closed the deal on The Gardener, which is the smaller, more personal film he wanted to direct next. But will Weitz commit to the back-to-back films, which are sure to keep him away from his family for several months?
What's the alternative, though? To bring on a director new to the franchise to helm its big finale? That doesn't make sense, and I'm sure Summit is preparing to empty their wallets on this one in order to line up the correct pieces. Sources claim the studio wants Weitz to finish the job, though they haven't yet made him an official offer. What do you want to see happen?
