HBO has released a new trailer for tennis mockumentary 7 Days In Hell, and it features an impressive cast of comedy and tennis stars.

The movie will tell the story of the longest tennis match ever played, between a brash American named Aaron Williams, played by Andy Samberg, and a genteel Englishman named Charles Poole, played by Kit Harington, who you may know as Jon Snow from Game of Thrones.

The film also features appearances from tennis stars John McEnroe, Chris Evert and Serena Williams, who plays Samberg's adopted sister, thanks to a "reverse Blind Side."

The movie will air on HBO on July 11, but can be seen early on the premium channel's streaming services, HBONow and HBOGo, beginning July 8.
