HBO has served a few volleys of upcoming tennis mockumentary 7 Days in Hell, following its SXSW debut last year, but with a July 11 premiere fast on the rise, so too is promotion heating up. Watch Jon Snow Kit Harington and Andy Samberg go at it in the full star-studded trailer for HBO’s 7 Days in Hell!

“If the pressure of winning Wimbledon wasn’t enough, now he’s got a dead body on his hands,” the announcer speaks of Samberg’s Aaron Williams, adopted sibling of Serena Williams, in a reverse Blind Side. “Second serve now, after killing a man.” So goes the second trailer for HBO’s 7 Days in Hell, a mock sports documentary HBO describes as:

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.

In addition to the stars listed above, the newest trailer also features the likes of Last Man on Earth star Will Forte, Fred Armisen, Girls favorite Lena Dunham, Serena Williams and John McEnroe, along with a cast that includes Mary Steenburgen, June Squibb (as the Queen!), Howie Mandell, David Copperfield, Chris Evert, Michael Sheen and Karen GIllan.

7 Days in Hell will premiere on Saturday, July 11, but seems well-worth the price of admission by its above trailer.
