The "Twilight" series has not yet had a stake through its heart. The fourth installment, "Breaking Dawn Pt. 1" was as big as ever, and the fifth, "Breaking Dawn Pt. 2" is still five months from release with a new trailer is set to debut on Wednesday. It's still a major cash cow for Summit (recently acquired by Lionsgate for $400 million, with the franchise as the crown jewel of the buyout), even as the parent studio's "The Hunger Games" has arguably eclipsed it in returns and press of late.

But the trouble is, that stake is a comin': Stephenie Meyer wrote a definitive end to her four-book saga, and once the last film hits in November, there's no more material to adapt. At present, at least, there are no more "Twilight" books, and no way of continuing Bella and Edward's story. The cash cow is running dry. The goose is no longer laying golden eggs. Stop your weeping at the back, it'll be alright.

But it wouldn't surprise many to learn that contingencies are already in operation: Bloody Disgusting reported over the weekend that internal discussions have already begun at the studio as to a continuation of the franchise. According to the site, it could take the form of a spinoff, a sequel, or possibly even a remake/reboot of the series, with new actors and a new take. There are clearly no firm plans in place, and Summit have already denied it, telling Deadline that, "We are not remaking 'Twilight.' We will happily support Stephenie Meyer if she decides to proceed in any way. But this will be the last one unless that should change." This would not, however, be the first time that a studio has denied something, and it's almost unthinkable that Lionsgate/Summit are sitting around crossing their fingers waiting for Stephenie Meyer to write another book. It may be a few years off, but we'd be very surprised if we didn't see a sixth "Twilight" film of some shape and form wasn't announced in the next few years.

But the question is, what should it be? The potential for a spin-off is already there. The novella "The Short Second Of Life of Bree Tanner," focusing on a minor supporting character for third novel "Eclipse" was released in 2010, and Meyer was working on a book called "Midnight Sun," which retold the events of the first novel from the perspective of Edward Cullen, until an internet leak of the first twelve chapters caused her to cease all work on both it, and any other "Twilight" novels that might have been in the works. Either -- a spin-off focusing on Bree, or an adaptation of "Midnight Sun," should it ever be finished -- could plausibly form the basis of another book, even if the latter in particular sounds like the single most pointless endeavor in the history of literature.
