HBO series like “Sex and the City” and “Entourage” made (or are making) the leap to the big screen. So it begs the question, could the hit show “Game of Thrones” do the same?

“I think it’s an option on the table, maybe,” said Kit Harington at Tuesday night’s Cinema Society screening of his new movie “Pompeii.” “It’s very filmic in its style already, so it’s possible.”

Harington started his red carpet interview by asking me a question: “Are those your crutches?” he said, pointing to a pair that belonged to another reporter. As he started to explain what drew him to “Pompeii,” he abruptly stopped talking. “One second.” Several publicists nervously fluttered on the red carpet as he bolted for the bathroom. “I just got very dizzy,” he explained, when he returned a few minutes later and resumed the interview.

“It was a big body transformation,” Harington said of his new role in “Pompeii.” “I had to go to the gym a lot.”

“It was what we called gladiator camp, four weeks prior to the start of the movie,” said his co-star Adewale Akinnuoye-Agbaje. “It consisted of four hours a day of workouts: two hours of intense fight training with swords and weaponry, an hour of weight training, then another hour of cardio, and that was covered with an 1,800-calorie diet, which was brutal.”

“Both me and Kit trained together,” Akinnuoye-Agbaje continued. “It was a really useful exercise. It allowed us to bond and form a relationship that leaps over into our characters onscreen. Kit had the sickest abs. I had the sickest guns, legs and some other things.”

The screening of the FilmDistrict and TriStar Pictures release was held at New York’s Crosby Street Hotel and included guests Candy Spelling, Paul Haggis, Carrie Preston and the film’s director Paul W.S. Anderson. The after-party was in the penthouse of the Standard East Village.
