Sex, drugs, accidental shootings, sports prodigies, career rises and falls, comebacks, endorsements, mullets, male nudity, and Taiwanese animation re-enactments of Swedish prison sex parties… HBO’s new sports mockumentary 7 Days in Hell, premiering July 11, has it all.

The movie — starring Brooklyn Nine-Nine Golden Globe winner and Saturday Night Live Emmy winner Andy Samberg as Andre Agassi-ish bad boy tennis star Aaron Williams and Game of Thrones star Kit Harington as his rival, dimwitted tennis prodigy Charles Poole — hits all the clichés sports doc fans have come to expect from series like ESPN’s 30 for 30, with all the over-the-top humor you’d expect when those docs get spoofed by an all-star cast, in an anything-goes venue like HBO.

Samberg, who returns for a third season of Brooklyn Nine-Nine on Sept. 27 and hosts his first Emmy telecast on Sept. 20, talks to Yahoo TV about his favorite funny moments from the movie, how the movie flips the script on full-frontal nudity, and gathering a cast that also includes Michael Sheen, Mary Steenburgen, Fred Armisen, Will Forte, Serena Williams, John McEnroe, June Squibb, Lena Dunham, Howie Mandel, Jim Lampley, David Copperfield, Soledad O’Brien, Chris Evert, and Karen Gillan.

He also shares the biggest perk of making the sports-themed project: free classic Nikes.

You’ve said you wanted to write a tennis comedy, and the three-day John Isner-Nicolas Mahut match from Wimbledon in 2010 was an inspiration, but are you also a fan of 30 for 30 and other sports documentaries?

First, I should clarify… me and Murray Miller are both executive producers. He is the sole writer, but we sort of brainstormed it all together. I don’t want to take away his writing credit. We’d been buddies since summer camp and then lived together in New York, and were friends in L.A., and now he’s a writer on Girls. We had had this idea, and then sort of revised the idea after the Isner-Mahut match lasted three days, to say, “What if a match just never ended?” For a long time it was just called, The Never-Ending Match. That was the pitch. When he got an overall deal at HBO, I called him and I said, “What if we adjusted this, and made it sort of like an HBO sports documentary, or a 30 for 30” — because, yes indeed, we both do love those, and watch all of them — “and then do it at HBO?” He loved that idea; so we brainstormed a bunch of stuff and he wrote this really incredible outline. We went in, pitched it to them, and they totally dug it, and he wrote it up and then we re-wrote it, and that was it.

Is it true that you shot it in three days? The shoot lasted about the length of the Isner-Mahut match?

[Laughs.] We shot all of the tennis in three days. All of Kit Harington’s stuff was shot over a three-day period. Most of it was shot in Palm Desert, and it was 122 degrees, and it was miserable. Then after that, I’d say there were probably like seven more days of pick-ups, getting people to do talking head stuff here and there. I think in the end, it ended up being an 11- or 12-day shoot total.

7 Days in Hell hits pretty much every sports documentary cliché. Was there something in particular that you were excited to spoof?

Oh, a lot of stuff. Getting to have John McEnroe and Chris Evert and Jim Lampley doing the color commentary… anytime you have them, completely straight-facedly talking about these insane things that are happening on the court, it just tickles me. It gives it that authenticity that we were really hoping for. There’s these certain moments that sort of all congeal, where we shot on these old cameras, because our director, Jake Szymanski, wanted to shoot with old cameras so it really felt vintage, and you have [these athletes and announcers] commenting on it, and the court looks real, and you feel like you’re at Centre Court at Wimbledon. And then when that level of authenticity comes together in support of the dumbest joke we could think of, that for me feels like the payoff of wanting to make this.
