‘7 Days In Hell’: Full Trailer For Andy Samberg & Kit Harington Comedy Doc Drops

Andy Samberg has met his match in Kit Harington in the trailer for “7 Days in Hell.”

HBO served up the full trailer for its comedy documentary starring Andy and Kit as rival tennis stars Aaron Williams, a mulletted American bad boy of the court and Charles Poole, a dim witted British tennis prodigy, who engaged in the longest match in the sport’s history.

The full trailer features cameos from Serena Williams (who plays herself, and Andy’s character’s sister), Will Forte, John McEnroe, Lena Dunham (in denim and a mullet), Fred Armisen, June Squibb (who appears to be playing a very sassy Queen), Chris Evert, Soledad O’Brien (who Kit’s character confuses for Bryant Gumbel) and Mary Steenburgen.
