When tennis superstars Aaron Williams and Charles Poole stepped onto the court to face off, they never envisioned their meeting would become the longest and greatest match of all time. Golden Globe-winner Andy Samberg ('Brooklyn Nine-Nine') and 'Game of Thrones' star Kit Harington (who plays Jon Snow in the hit series) head up the cast of this outrageous mockumentary about the ultimate tennis match--a grueling seven-day, five-set marathon between the hyper-malcontent Williams and the dim-witted prodigy Poole. Joining them in the cast are Fred Armisen, David Copperfield, Lena Dunham, Chris Evert, Will Forte, and many others.
