His mere presence sent teens worldwide into shrieking fits of excitement, yet Kellan Lutz never once lost his cool. The actor achieved cult-like fandom after playing the muscular and imposing vampire Emmett Cullen in "Twilight" (2008) and the subsequent sequels, "The Twilight Saga: New Moon" (2009) and "Eclipse" (2010), based on the best-selling novels by Stephenie Meyer. Prior to his fanatical following as a thirsty bloodsucker, the actor had earned his acting stripes as a struggling sitcom star opposite Lisa Kudrow on the critically-lauded but ultimately short-lived series "The Comeback" (HBO, 2005), as an Iraqi soldier on the deadly frontlines in the miniseries "Generation Kill" (HBO, 2008), and as a suburban teen visited by Freddy Krueger in his dreams in "A Nightmare on Elm Street" (2010), a remake of the horror film classic. Lutz may not have possessed the Byronic presence of his "Twilight" co-star Robert Pattinson, but his portrayal of a protective and fun-loving vampire in the blockbuster film saga proved there was no shortage of talent and charisma under all the brawn.
