Making that transition from a beloved film series with a fervent fan base can be tricky. Do you stick to the same kinds of roles that people came to love you for and maintain the safety of familiarity? Or do you veer drastically in the other direction to prove to the world that you have range - that you're so much more than just a mopey teenage girl or a hunky set of abs?
"Harry Potter" star Daniel Radcliffe, for example, has successfully made choices that showcase his versatility, from appearing on stage naked in a Broadway production of "Equus" to the gothic horror film "The Woman in Black." His "Harry Potter" co-star, Emma Watson, played a damaged party girl this year in "The Perks of Being a Wallflower," a character who couldn't have been more different from the fastidious Hermione Granger.
The three core "Twilight" stars have all struck while the iron was hot, making a variety of films in between the five "Twilight Saga" installments about high schooler Bella Swan and the vampire and werewolf who competed for her affections.
Stewart was the best known of the "Twilight" trio before being cast as Bella. She'd played Jodie Foster's daughter in the 2002 thriller "Panic Room" and a commune singer who befriends Emile Hirsch's character in Sean Penn's Oscar-nominated "Into the Wild" (2007).
Her choices between the "Twilight" movies have run the gamut, from playing a young Joan Jett in the 2010 biopic "The Runaways" to a fairy-tale warrior princess in this summer's "Snow White and the Hunstman." Next month, she'll appear in "On the Road," based on the iconic Jack Kerouac novel.
"Kristen seems to do a lot of indie movies. 'Snow White and the Huntsman' is more of an outlier in terms of being a blockbuster," said blogger and "Twilight" expert Cleolinda Jones, author of the "Movies in 15 Minutes" series. "But it seems like she's got the kind of personality where she's got to do what she has to do ... she's not thinking in terms of career strategy."
Andrei Constantinescu of the Dallas-based Legacy Casting says he'd like to see Stewart mix it up even more.
"Her non-'Twilight' film choices are bold and different to a point, but her dark and broody acting style, similar to her real-life persona, is a bit played," said Constantinescu, whose work as an extras casting director includes the TNT series "Dallas." ''I'd love to see her in a romantic workplace comedy like 'The Devil Wears Prada.'"
Pattinson has made some of the most daring and impressive choices of the three of them. Before being cast as the swoony vampire Edward Cullen, the lanky British actor appeared in another blockbuster franchise as Hogwarts student Cedric Diggory in 2005's "Harry Potter and the Goblet of Fire." In 2009, he played Salvador Dali in the barely seen "Little Ashes," and last year he starred opposite Reese Witherspoon in the circus romance "Water for Elephants" - although Associated Press reviewer David Germain wrote there was "barely a spark" between the two.
But Pattinson also has worked with the likes of David Cronenberg, starring this year in the acclaimed Canadian director's financial drama "Cosmopolis," which takes place almost entirely inside a limousine. And he'll soon work with Cronenberg again in "Maps to the Stars," and also begin shooting Werner Herzog's "Queen of the Desert."
Jones says Pattison has wisely chosen to parlay his "Twilight" fame to collaborate with serious directors and actors.
"He knows he has a certain box office appeal so the fangirls are going to see him no matter what he's in," she said. "People are willing to work with him the first time, they see all this potential he has, then they want to come back and work with him again."
Constantinescu echoed those thoughts: "He's the one to watch for additional films down the line," he said. "We are just scratching the surface with Robert."
Then there's Lautner, who was just 15 when he auditioned for the role of the sensitive, muscular werewolf Jacob Black. He'd appeared in a few films by then, including playing the title character of Sharkboy in 2005's "The Adventures of Sharkboy and Lavagirl in 3-D." In between the "Twilight" films, he stuck to lighter fare. He was part of the ensemble cast of 2010's "Valentine's Day" in a romantic subplot opposite Taylor Swift.
But Lautner's leading-man debut was last year's "Abduction," a title that naturally inspired plenty of puns about his famously toned frame. The thriller from director John Singleton found Lautner playing a high-school student who gets caught up in a web of intrigue. AP reviewer Jake Coyle wrote that Lautner "handles himself reasonably well" but the script was the film's "major deficiency."
Constantinescu says he doesn't expect Lautner will stray far from crowd-pleasing fare.
"He's very good at playing the young, muscular jock or hero," he said. "Similar to Kristen, I'd love to see roles that offer Taylor different objectives than to be the hero, take his shirt off and save the day. However, I'm not sure that the public would believe him as anything more than the borderline superhero he has become famous for."
Jones agreed: "He's not going to be in the next mumblecore indie movie," she said of Lautner. "I'm not sure where he goes with this after age 30. His current trajectory is kind of clear, but I don't know what happens when he grows out of his dimples."
