Last Twilight Film Will Likely Split in 2

The Twilight vampires have followed Harry Potter and company into the world of hugely successful films—and the last installment could take a cue from the boy wizard. Summit wants to split the final novel, Breaking Dawn, into two pictures just like Warner Brothers did with Harry. There are a few hurdles, however, not the least of which is how much it will cost—Variety runs down a few:

• Will New Moon director Chris Weitz agree to it? The back-to-back shooting schedule is tough, and he has said he's determined to direct non-Twilight film The Gardener next.
• The cast is currently only locked for four films, and a fifth would mean big raises for all key members—possibly in the eight-figure range for the three principals.
• Summit will have to reopen negotiations and get author Stephenie Meyer's approval before splitting the book.
