Jacob grabs a rare moment alone with Bella in "Eclipse," the third film in the saga. There's one more book, "Breaking Dawn," which will be split into two films.
In the second film, "New Moon," Bella and Edward are inseparable until a major threat rips them apart.
In "New Moon," the sequel to "Twilight," Bella starts off deliriously happy and in love with the vampire Edward Cullen, but falls apart and becomes a shell of herself after he leaves her. When she realizes that she hears Edward's voice and sees visions of him whenever her life is in danger, Bella engages in high-risk activities as a way to hang on to her memories of him.
Edward watches on as Bella chats with her friend Jacob Black in "New Moon." Jake, who harbors a not-so-secret crush on Bella, brings her back to life after she is crushed from the breakup with Edward.
After Edward breaks up with her, Bella lies in the forest in shock overnight until her police chief dad, Charlie (played by Billy Burke), scours the woods for her with his squad. When they find her, she is unresponsive and remains in a deep depression for months.
In "New Moon," Jake transforms from a lanky teen to a beefy hunk, thanks to his new werewolf status. To prepare for the physical change the role required, Taylor Lautner started hitting the gym and eating 3,200 calories a day to gain muscle so that his physique would better resemble Jacob's.

English actor Pattison moved from modeling to the role of Cedric Diggory in "Harry Potter and the Goblet of Fire" before taking on the role that would make him famous, that of hunky vampire Edward Cullen in "The Twilight Saga."
Kellan Lutz plays Emmett Cullen in the "Twilight" movies. He's considered Edward's brother in the film and books, but in reality, the young vampires aren't related -- they were brought together by an older vampire and present themselves as a family to the outer world. Lutz bulked up for the films, but insists it hasn't interfered with his addiction to gummy bears, gummy worms, chocolate and other sweet treats.
Peter Facinelli (husband of "90210's" Jennie Garth) and Elizabeth Reaser play the Cullen parents, Carlisle and Esme, in the "Twilight" movies. Carlisle, a doctor, managed to gather his small band together as a family and convince them to kill only animals to slake their bloodlust. They occasionally clash with other vamps who aren't quite as compassionate where humans are concerned.
Billy Burke plays Bella's father, Charlie, and serves as the chief of police in their small rainy town of Forks, Wash. The Cullen vampire clan resides in the damp town because it's low on the bright sunshine that would reveal their non-human identities. Vampires in the "Twilight" universe sparkle brightly in direct sunlight.

His fascinating backstory includes a history as a Confederate soldier in the Civil War and years spent training newborn vamps to learn to control themselves. He has the power to feel and manipulate the emotions of others.
Vampire James, played by Cam Gigandet, is considered a "tracker," and once he discovers Bella's human scent, plans to pursue her until her death. In "Twilight," he convinces her that her mother is in danger and thus forces her to sneak away from Edward and meet him in the Arizona ballet studio where she studied as a child.
Fiery-haired Victoria makes up the third and final member of Laurent and James' coven. Her mate dominates the action in the first book, "Twilight," but by the third book, "Eclipse," Victoria takes center stage to try and wreak bloody revenge on Bella and the Cullens. Rachelle Lafevre, center, plays Victoria in the first two films, but when she needed time off for a movie, she was fired and replaced by actor Ron Howard's daughter, Bryce Dallas Howard, right.
While Jacob Black is a Native American in the books and the films, actor Taylor Lautner himself is not. He was nearly replaced for the second film when moviemakers thought he couldn't convincingly pull off the bulk required for the role, but an impressive workout routine changed that.
