Natalie Dormer has been very busy as of lately not only does she portray Margaery Tyrell in the hit series "Game of Thrones" but she is also in the midst of shooting the final installments of the "Hunger Games" franchise.

According to Entertainment Wise, during the HBO star's appearance on "Late Night with Seth Myers" on Tuesday she chatted about her career and her completion of the London Marathon this month.

The 32-year-old told the host that her first marathon was "absolutely incredible, I might've caught the bug. I'm thinking about my next one".

Dormer admitted that it was another famous face who convinced her to attempt the marathon.

She explained, "I was sort of egged on. I was here In New York shooting Elementary with Johnny Lee Miller and he does a lot of marathon running and he was kind of like 'just do it'.

"So I did but I made the mistake, or had the advantage, of telling everyone that I was going to run it in under four hours. I made that promise in October but I did it in 3:50."

The Blonde beauty admitted that her role as Cressida in "The Hunger Games" movies proved to be beneficial for her marathon training.

Natalie Dormer said, "With The Hunger Games there is so much running around - I'm carrying a gun and wearing big heavy army boots - so because it's quite physical it helped me with the training for the marathon and keeping up with the likes of Liam Hemsworth."

She added, "He's a big guy holding the gun with his little finger. But I got fit!"

The star's show has been receiving a lot of attention following her character, Margaery Tyrell witnessing her husband, King Joffrey's death at the Purple Wedding,

Dormer explained the long awaited scene. She said, "It's cut together so well. It's kind of like a whodunit."

She added, "You see all the characters moving around and you're following the goblet or the pie, you're like 'where is it happening."

"It was really fun to shoot and we all got to be together which we never get to do which was fun. A lot of scrabble was played, on iPads. All us girls are sitting there with our skirts up around our necks playing scrabble - it's very glamorous."
