Kit Harington Trades His Sword For A Tennis Racket in HBO's '7 Days in Hell' Trailer [VIDEO]

The world is still reeling from the unexpected (if alleged) death of Jon Snow in the season finale of 'Game of Thrones.' Although Kit Harington, who plays the newly elected Lord Commander of the Night's Watch, has insisted that Jon Snow is dead, several fans continue to rally their theories that Jon Snow will return in the upcoming season.

Jon Snow's fate may still be undecided until 'Game of Thrones' releases its sixth season. In the meantime, Harington's fans will not need to change the channel to get a glimpse of their favorite crow.

The actor returns to HBO in '7 Days in Hell,' the fake tennis documentary starring Andy Samberg, Karen Gillan, Lena Dunham, Will Forte and Michael Sheen. HBO has just released a full trailer of the mockumentary, showing Harington in a white headband and matching white shorts.

Kit Harington stars as Charles Poole, an English tennis star who battles it out with Aaron Williams (Samberg) in an epic seven day match to win Wimbledon.

The trailer offers a short biography on the rival tennis players. Poole is determined to win since Wimbledon has not been won by an Englishman for a long time. Meanwhile, Williams is considered "the bad boy of tennis," having been raised by a black family in what is being considered a "reverse Blindside."

The short film also features cameos from Serena Williams, John McEnroe, Howie Mandel and David Copperfield.

Kit Harington has previously told Jimmy Kimmel that Jon Snow's death on 'Game of Thrones' would mean the end of his career. Although there haven't been any new updates on what the actor will do after the show, he has been cast in Xavier Dolan's film 'The Life and Death of John F. Donovan.' Harington will play the title role and star opposite Academy Award nominee Jessica Chastain.

'7 Days in Hell' will premiere on HBO on July 11, 2015.
