A post about the prettiest eyes [& boobs] in Hollywood: Alexandra Daddario in Vanity Fair Magazine

"I was obsessed with Nancy Drew growing up—I couldn't get enough," says Alexandra Daddario, the breakout star of television's most talked-about new drama, True Detective, starring Matthew McConaughey and Woody Harrelson. "There is nothing better than a really cool mystery: you don't know what's going to happen, so you keep turning those pages or watching that series."

But the role of Lisa Tragnetti, which gave viewers an eyeful—the Upper East Side native bared all in a titillating handcuff scene with Harrelson—almost didn't happen for her. "I never read for Lisa," Daddario says of her auditioning process. "I initially read for the part of Beth [yet another of Harrelson's character’s mistresses, played by Lili Simmons], but they wanted me for this bolder, more adult role."

Prior to this, the 28-year-old Brearley and Professional Children's School alum was known for her turns playing teenagers in Texas Chainsaw 3D and the Percy Jackson films. "I've been playing younger for so long, it's exciting to do things that I've never done before," she says. (Daddario got her start with commercials when her Merrill Lynch-lawyer mother and her father, a prosecutor for the U.S. Attorney's Office, encouraged her to do something more creative than they had.) Especially when acting opposite Harrelson. "He is a really funny, nice guy even when my character was pretty racy," she says. "I loved that Woody kept it sort of business as usual."

Harrelson was equally impressed. "She was incredibly focused, hardworking, and willing to try anything. She's got those hypnotic eyes that people only get by wearing contacts, but hers are real and induce a feeling of euphoria. There was a scene where I come in, fight the guy she's with, and she yells at me, and that was a little more challenging, but she has an ability to be flexible and real inside the scene."

Come 2015, audiences will see Daddario in a different guise, as the heroine in the upcoming disaster epic San Andreas, with Dwayne "the Rock" Johnson. "Essentially a giant series of earthquakes hits Los Angeles, and I have to play this tough chick," she says. "You'll find me being a lot more heroic than I am in my real life."
