Olivia Wilde has a intellectual pedigree. Her father and uncle, both named Alexander Cockburn are fiery Irish journalists and her mother, Leslie Cockburn, is a producer for CBS’s “60 Minutes.” So how did she arrive at the name Wilde?

She picked it in honor of author Oscar Wilde the Irish writer, poet and aesthete who captivated Victorian London society, but died penniless in Paris.

Needless to say, Olivia, 26, possesses the same free spirit, which is on display in the latest issue of Vanity Fair.

Wilde’s film resume is relatively short. She appeared in “The Girl Next Door,” “Alpha Dog,” “Conversations with Other Women” and ‘Turistas.”

Oddly, she’s best known for her role on “The O.C.” as Alex Kelly. She also appeared on the television show “House” in 2007.

But Wilde has a feature role in “Tron: Legacy,” which reprises the 1982 ground-breaking Sci-Fi film, “Tron.”

Jeff Bridges and Bruce Boxleitner return in their original roles, while Garrett Hedlund portrays Flynn’s now-adult son, Sam. Beau Garrett, Michael Sheen and John Hurt also appear.

Wilde plays Quorra, and the role required her to wear a futuristic body suit that was so tight she needed an assistant to help her get in and out of it

“My costume is actually the toughest, most badass thing I’ve ever seen,” she told the December issue of Playboy.

In the Vanity Fair spread, Wilde poses semi-submerged in a shallow pool wearing a white dress.

Wilde talks about her new projects and her upcoming movie role in the western “Cowboys & Aliens” with Harrison Ford.

“What’s great is that I don’t have to play the weeping lady in distress,” she said. “I get to play a pretty cool and powerful woman.

“I love the horses, I love the guns. For an actor, to be in a Western feels almost like a rite of passage.
