If you were distracted by Game of Thrones on Sunday, you probably missed the promos for 7 Days in Hell. 

What’s that? Well, 7 Days in Hell is an HBO movie starring Andy Samberg and Kit Harington (from Game of Thrones). 

Samberg and Jon Snow in the same movie? brain explodes

This fake mockumentary follows two pro tennis players in 2004. Harington and Samberg face off in a one-week tennis match, the longest match ever.

I think Indiewire put it best when they described it asBlades of Glory but with rackets.” Andy Samberg’s character actually looks like he could have come straight from the Blades of Glory world, donning a ridiculous mullet that’s terrible even for the primal days of 2004.

That said, the look lines up well with his character, Aaron Williams. Williams is a superstar bad boy returning to the pros after his early retirement landed him in a Swedish prison.

On the other side of the net, Kit Harington looks like he could pass for a tennis pro. He rocks a man bun as Charles Lloyd Poole, a prodigy who’s prettier than he is brainy.

Now that’s what we call character development.

7 Days In Hell

If 7 Days in Hell seems like a giant SNL digital short, it kind of is. SNL alum Samberg was a co-creator, and it was directed by Jake Szymanski (Funny or Die, SNL Digital Shorts).

The movie rocks one hell of a lineup of fellow SNL alums as well as other comedy stars owning the small screen – Fred Armisen, Lena Dunham, and Michael Sheen to name a few. In addition to comedy A-listers, 7 Days in Hell will also feature interviews with tennis pros like Serena Williams, John McEnroe, and Chris Evert.

After all, it’s very, very loosely based on the 2010 Wimbledon matchup between John Isner and Nicholas Mahut that lasted three whole days, which is actually the longest match in tennis history.

The movie premiered at South By Southwest this year. In a fairly positive review from Hollywood Reporter, we’re told that the film doesn’t try to give you side plots and sticks to the mockumentary style the whole time.

(SIDENOTE: That doesn’t mean there aren’t hilarious B-plots, like Michael Sheen’s sweaty, cigarette-reeking TV host who has a super weird attraction to Harington’s character.)

The same review also says the movie features lots of genital-centric humor and what’s been described as an all male orgy scene that’s “graphically depicted in CGI recreations.”

So, there that is.

The 43-minute comedy fittingly premieres on the first weekend of the 2015 Wimbledon tournament (July 11th). And following in the footsteps of Netflix and Hulu, you can catch it on HBO and HBO NOW.
