Tennis is a lot better than most people crack it up to be. Sometimes, you’re treated to amazing points like this one between Novak Djokavic and Rafael Nadal just a couple days ago in the French Open.

But even better than that, is HBO’s trailer for “Seven Days in Hell,” starring Andy Samberg

Samberg plays Aaron Williams, who is locked in a seven-day-long tennis battle with Charles Poole, played by Kit Harington — also better known by Jon Snow from Game of Thrones. And like you’d expect, looks like Samberg acts the crap out of it with his usual over-the-top antics.

The mockumentary appears to have all of the typical Samberg lovableness. But if that wasn’t enough, the supporting cast is also made up of Serena Williams, Lena Dunham, Will Forte, Karen Gillan, Michael Sheen, June Squibb, Soledad O’Brien, Howie Mandel, Fred Armisen and Mary Steenburgen.
