7 Days in Hell premieres July 11 on HBO.

Gifted Youth's Jake Szymanski directs this ~40min 'mockumentary' starring Andy Samberg and Kit Harrington for HBO about the longest tennis match in history ala ESPN's 30 for 30. The film features cameos from  Fred Armisen, Serena Williams, Will Forte, Soledad O'Brien, and of course Jon Hamm. Peep the AV Club's writeup/review below.
