A very funny trailer’s dropped for the spoof sports film 7 Days In Hell.

The fictional documentary starring Kit Harington and Andy Samberg, focuses on a 7 day tennis match between two great rivals.

Jon Snow has ditched the beard for his role as Charles Poole, a simple, idiotic, English tennis player, facing a brash, crude, American opponent, Aaron Williams.

Williams channels all the elements of a bratty, petulant, John McEnroe, while opting to go with an impressive Andre Agassi look, with a long flowing blonde mullet.

The idea behind 7 Days In Hell, is influenced by the real life Wimbledon match between John Isner and Nicolas Mahut. In 2010, the relative unknowns became household names, after their epic tennis match took three days to resolve. The 5th set alone went on for over 8 hours, finishing with the ridiculous scoreline 70-68.

7 Days In Hell features a great support cast, starring in the film is Girls creator Lena Dunham, Michael Sheen, Serena Williams, Karen Gillan, Fred Armisen, and magician David Copperfield.

During the trailer, Aaron Williams flips off the Queen, knocks out a line judge, tries out a denim tennis outfit, and cavorts with a female streaker.
