Andy Samberg unite4: good - H 2014

HBO is headed to Wimbledon.

The premium cable network is teaming with Girls writer/co-EP Murray Miller and Brooklyn Nine-Nine star Andy Samberg for 7 Days in Hell, a mockumentary send-up of professional tennis, The Hollywood Reporter has learned.

The one-off HBO Comedy Event is described as a sports mockumentary starring Samberg and Game of Thrones breakout Kit Harington as fierce tennis rivals in an epic, seven-day match at Wimbledon. Samberg will play Aaron Williams, a superstar tennis "bad boy," while Harington is set as Charles Lloyd Poole, an Andy Murray-type prodigy and certified truck driver who takes on Williams at Wimbledon 2004.
