Watch: Andy Samberg And Kit Harington Are Tennis Rivals In First Trailer For '7 Days In Hell'

7 Days In HellWhile Andy Samberg is perhaps best known for his digital shorts as part of The Lonely Island crew, he’s proven with "Brooklyn Nine Nine" that his brand of comedy can work in larger doses. And while The Lonely Island are currently shooting a feature comedy, we’ll get our first taste of "Full Samberg" — perhaps more free-spirited here than in any other previous movie appearance — in HBO‘s "7 Days In Hell." And this first tease is pretty great.

"Game Of Thrones" star Kit Harington is the unlikely co-lead of this mockumentary that looks back on an infamous seven day long tennis match, the lengthiest in the history of the sport. Here’s the official synopsis: This sports “documentary” brings together Andy Samberg and Kit Harington for a look back at a pair of fictional players from the not-too-distant past, who played the longest and greatest tennis match of all time: a seven-day, five-set marathon that took literally everything out of them. In addition to highlights (and lowlights) from the match, the special looks back at the lives and careers of the competitors: Aaron Williams (Samberg), a hyper-malcontent, and Charles Poole (Harington), a dim-witted prodigy who carried England’s hopes for a tennis champion on his shoulders.

"7 Days In Hell" arrives on HBO on Saturday, July 11th at 10 PM. Watch below.
