"Game of Thrones" cast Kit Harington is proving Rolling Stone magazine's prophetic cover of being Hollywood's next golden boy as he makes the transition from the small screen to movies with "Spook: The Greater Good" and "Testament of Youth."

Kit Harington graced the April issue of Rolling Stone dressed in a tank top and showing off his biceps as he carried a falcon on his left hand. The cover story featuring the 27-year-old actor is titled, "The Man Who Would Be King."

In a series of snaps published on MailOnline, "Game of Thrones" cast Kit Harington has resumed filming for "Spooks," which is based on a nine-year TV series starting in 2002, after making a side trip to Cannes for the animated film "How to Train Your Dragon 2."

The "Pompeii" actor didn't stop the rain from playing his role seriously, as he looked a bit scruffy after still sporting the long locks of Jon Snow.

In "Spooks," "Game of Thrones" cast Kit Harington plays Will Crombie who will team up with MI5 Intel Chief Harry Pearch (Peter Firth) to find the terrorist fugitive before time runs out for London.

"Game of Thrones" cast Kit Harington will be next seen on "Testament to Youth," which is a drama set during WW I. It tells the story of Vera Brittain, who leaves the university to become a nurse who is then deployed to London, Malta and France. Kit Harington will play her fiancé, Roland Leighton.

In the Rolling Stone issue, Kit Harington admitted that he find so much connection with his "Games of Thrones" character Jon Snow.

"The thing that drives both of us is more similar than you might think - he's driven by ambition. I've always been very ambitious too. Snow is a good person who believes in what he's doing, but that's the struggle: balancing duty with ambition," he said.
