The DVD for "The Twilight Saga: Eclipse", the third installment of the blockbuster vampire series, will be available December 4, but you can already pre-order it on Amazon.
The first three movies have raked in $1.8 billion in global box office.
That's just revenues from theaters.
DVD sales, book sales, merchandising, add it all together and the love story of Bella and Edward has sucked up a lot of cash to keep the blood of commerce flowing.
Vampire mania has spawned offspring like "True Blood" and "The Vampire Diaries", though nothing may be better than the original campy "Dark Shadows" or the fun moxie displayed in "Buffy the Vampire Slayer".
