As he wraps up filming the third season of HBO’s wildly popular fantasy series Game of Thrones, Jon Snow himself Kit Harington is lining up a high profile feature film to shoot during his upcoming hiatus.  Variety reports that Harington is in talks to star in director Paul W.S. Anderson’s period pic Pompeii.  For those unfamiliar, the city of Pompeii was destroyed and buried during a catastrophic eruption of the volcano Mount Vesuvius in the year AD 70.  Anderson’s film uses this disaster as the backdrop for the story of a shipping tycoon’s slave named Milo.  Hit the jump for more details.Milo dreams of the day he can be free and marry his master’s daughter, but soon finds out that she’s been promised to a corrupt Roman senator and he’s been sold to an owner in Naples.  As Mt. Vesuvius erupts, Milo heads back to Pompeii in order to rescue his love and his best friend, a gladiator trapped in the coliseum.  Downton Abbey creator Julian Fellowes recently performed a script rewrite, and Anderson previously told Steve that the pic will be rated PG-13.  The director also drew comparisons to James Cameron’s Titanic in that he hopes the audience gets so swept up in the story that they briefly forget about the impending doom.Anderson also said that he’d like to explore the political machinations of a corrupt city in addition to the film’s love story, which I guess is where the slave trade comes in.  Harington was previously in line to play King Arthur in the big budget fantasy film Arthur & Lancelot until Warner Bros. put the brakes on the project due to budget issues.  Should Game of Thrones be renewed for a fourth season (it will be), Harington will likely be needed back on set towards the latter half of next year, so I imagine production on Pompeii will begin early next year.
