How old the stars of 'Twilight' were compared to their characters' ages

"Twilight" begins with Bella moving from Phoenix, Arizona to Forks, Washington to live with her dad.

Stewart was already an established actor when she landed the role of the "Twilight" protagonist, having starred in movies like "Panic Room" and "Into the Wild."

Technically, Edward was more than 100 years old. He was turned into a vampire in 1918 as he was on the verge of dying from Spanish influenza.

Before playing a brooding vampire in "Twilight," Pattinson starred as Cedric Diggory in "Harry Potter and the Goblet of Fire."

Jacob was 15 in the first movie. Jacob became part of a love triangle with Bella and Edward as the franchise went on.

At the time, Lautner was known for roles in "The Adventures of Sharkboy and Lavagirl in 3-D" and "Cheaper by the Dozen 2."

He was a police chief in Forks and had an affinity for steaks. Charlie's age wasn't specified in "Twilight."

Before starring in the "Twilight" franchise, Burke had roles on TV shows like "Gilmore Girls," "Law & Order," and "24."

He was best friends with Charlie and his age was unclear. Billy and Jacob were part of the Quileute tribe.

Before "Twilight," Birmingham guest-starred on shows like "Buffy the Vampire Slayer," "Charmed," and "Veronica Mars."

Carlisle and the Cullen family distinguished themselves from other vampires because they hunted animals, not humans.

Before "Twilight," Facinelli starred in the '90s movie "Can't Hardly Wait" and the drama series "Fastlane."

Carlisle and Esme moved from town to town every couple of years with their adoptive children to avoid suspicions about their unchanging physical appearances.

Outside of "Twilight," Reaser guest-starred on shows like "Law & Order: Criminal Intent," "The Sopranos," and "Grey's Anatomy."

Alice could see the future through visions.

Greene had only been acting professionally a couple of years before she landed the role of Alice.

Jasper, also pretending to be a high schooler, could feel and manipulate people's emotions.

Rosalie was far less welcoming toward Bella than the rest of her family when they first met.

At the time, Reed was known for starring in the film "Thirteen." She cowrote the script with director Catherine Hardwicke, who also helmed "Twilight."

The running joke among the Cullen clan was that they accumulated a plethora of graduation caps because they repeated high school so often.

Before "Twilight" fame, Lutz guest-starred on "The Bold and the Beautiful," "CSI: NY," "Heroes," and "Generation Kill."

She was also a junior, making her around 17 years old.

At the time, Serratos was also known for her recurring role as Suzie Crabgrass on the Nickelodeon show "Ned's Declassified School Survival Guide."
