After that heart-breaking season finale for Game of Thrones you might think you won’t see Kit ‘Jon Snow’ Harrington for some time. But guess what? He’s making a lead appearance in the HBO Original mockumentary, 7 Days in Hell , about the (fictional) longest tennis match ever. His partner in crime and on-screen opponent is comedian Andy Samberg, who plays a mullet sporting tennis player who was raised by the Williams family (the one with Venus and Serena… yep, go figure).

Check out the hilarious trailer.
