When I first saw the headline, “HBO Releases Trailer for ‘7 Days in Hell’,” I thought it was going to be about something really serious. Well I was wrong. 7 Days in Hell is a faux-documentary that stars Andy Samberg and Kit Harington and is about a fictional tennis match that lasts for seven days.

Tennis legends Serena Williams and John McEnroe are also featured in the trailer as tennis legends being interviewed about the match. Comedian Will Forte will also be in the program that airs on July 11th on HBO.
