Wright spoke to People magazine about following the "paleo diet" for getting back into shape to play the shrewd and sexy Claire.

"I'm trying to do the paleo diet. No carbs. I've got to get thin for the show," she said.

The 48-year-old actress revealed that she also goes running to keep fit.

"I ran on the beach this morning," Wright said. "Running gets everything done, doesn't it? Covers it all."

But this does not meant that Wright is all about exteriors and would go the extra superficial mile for a part. 

Wright graced the cover of Town & Country's June issue, and she spoke to the publication about acting and playing Claire on House of Cards.

The actress suggested that she was skeptical about taking on the role of Claire Underwood in the Netflix political drama when producer David Fincher approached her because she worried she might need to go under the knife to play the part. The 48-year-old actress didn't want to get any cosmetic surgery done to be able to take the role, and was prepared to turn it down.

"I was sitting there going, 'You're 45, and you're not gonna get a face-lift,' " she said. "I was really considering that stuff, because in Hollywood the pressure's there. You better lift that face and pump those lips and hike those boobs! And I was like, 'I don't want to do that. I'm going to get older. I'm going to have wrinkles!'"

The third season of House of Cards will film in Maryland, where the first and second seasons were also shot. Initially, the continuation of filming of the third season of the Netflix series was fraught with troubles over the past few weeks as the producers weren't getting permission from the State of Maryland. But the issue was finally resolved on April 25.
