The full-length trailer for ‘The Twilight Saga: Breaking Dawn – Part 1’ has been unleashed on the web.

Film producers teased fans last weekend by releasing a 15-second clip of the trailer, which sparked a firestorm of discussion and speculation about the film.

‘Breaking Dawn – Part 1’ will be the first part of the fourth and final installment of the popular film adaptations of Twilight series of books, written by Stephenie Meyer.

The film stars Robert Pattinson as Edward, Kristen Stewart as Bella, and Taylor Lautner as Jacob.

The trailer opens in an idyllic scene at Edward and Bella’s wedding, as Bella’s father Charlie walks her down the aisle. The trailer then goes on to offer a glimpse of Jacob’s heartbreak as he says his final goodbye to Bella.

The happy nature of the trailer quickly fades once it is clear Bella is pregnant with Edward’s child. Fearful of what they believe to be an immortal child, the Volturi clan of vampires and a group of werewolves led by Sam Uley set out to kill Bella and her unborn child.

Neither Edward nor Jacob intend to go down without fighting for their love, with Edward proclaiming “They’re not going to touch her” as Jacob warns him of an upcoming attack. During the standoff, Jacob addresses the wolf pack he deserted, saying “If you kill her, you kill me”

Pattinson recently revealed that he and co-star Kristen Stewart destroyed a bed during the filming of the infamous Breaking Dawn sex scene.

‘The Twilight Saga: Breaking Dawn – Part 1’ is due for worldwide release on November 18.
