Jon Snow and Andy Samberg combined their talents to create this ridiculous HBO project – 7 Days in Hell. Kit Harington will face off against Andy Samberg in a tennis-themed mockumentary, which tells the (fake) story of two rivals who battled it out on the court for seven days in a row in an epic match.

According to reports, the mockumentary will feature a number of cameos and a 43-minute run time. Check out the teaser below:
