Summit declined to comment on the situation. But the studio wants to move quickly to pull the trigger on the two movies -- which it won't until the talent deals are further along -- and it isn't afraid to recast if agreements can't be reached. Plus, it has even more reason to be concerned about costs this time around. As is typical with blockbuster franchises, the "Twilight" movies are becoming more expensive with each installment. The leads are going to fare especially well if "Breaking Dawn" is split into two parts. The trio were initially signed for three films (remember, this was back when "Twilight" was a low-budget adaptation of a niche YA novel), but in the spring of 2009 -- after the first movie became an international hit -- they renegotiated all their deals so Summit could lock them for a fourth movie.

The studio then realized that "Breaking Dawn," with its 900-plus pages and narratives told from two perspectives, was dense enough to be split into two installments (as Warner Bros. announced it would do for the final "Harry Potter" book). Just one problem: The cast wasn't signed for a fifth movie. They're all huge stars now, with Lautner in particular running up his quote to the $7.5 million range, so another renegotiation commenced.

That meant ponying up big-time for the leads, which would make the final movie more expensive than the others ("Eclipse," which hits theaters June 30, is costing around $65 million, a figure sure to be dwarfed by the fourth and fifth, even if costs can be amortized by shooting them at the same time). Summit is still holding out the option of simply doing one "Breaking Dawn," although multiple sources say they'd be shocked if the fifth film doesn't happen. "This thing is gonna be two movies," one source says. "With or without the cast intact." Meyer has already signed off on the plan to make two — a key hurdle, given the approval rights she has in her deal.

Summit also is eyeing another cost-cutting measure for the final installments. A deal is currently being negotiated to move the production to Louisiana (the first was shot in Portland and the second two in Vancouver and Italy). Luring "Twilight" would be a huge "get" for the state -- and, given the tax credits, a money-saver for the studio.

"Twilight" has thus far been the rare tentpole franchise made on a non-tentpole budget. It'll be interesting to see the lengths that Summit will go to to keep it there. Booting an actor from the final installment of a successful series could be a risky move, though we're betting that as long as their precious Bella, Edward and Jacob return, fans would get over any disappointment pretty quickly.

Jag hoppas att lite av det stämmer som att Breakig Dawn kanske delas till två filmer men jag vill inte ha några skådespelarbyte :( Alla är så bra!

Hoppas Summit går ut med mer info snart :D
