Watch: Andy Samberg, Kit Harington cause a racket in HBO tennis movie

If you're still mourning the loss of Jon Snow (and actor Kit Harington's curly locks), then you're in for a treat in this new trailer.

The (ex?) Game of Thrones star goes full-man bun in HBO's upcoming 7 Days in Hell, his entirely random (but delightfully ridiculous) new tennis mockumentary with Andy Samberg. In the film, premiering July 11, Samberg and Harington play fierce rivals embroiled in an irreverent, seven-day tennis match. And while the first teaser gave us plenty of sweating and scowling, this new trailer offers a better peak at the star-studded cast, which includes Serena Williams, John McEnroe, Fred Armisen, Will Forte, and (national treasure) June Squibb.

Come for the man bun, stay for ... whatever Lena Dunham is rocking here.
