Fred Armisen has landed a Hell of a role…

The 47-year-old half-Venezuelan actor and former Saturday Night Live star has landed a role in HBO’s original comedy movie 7 Days in Hell, starring Armisen’s former SNL cast mate Andy Samberg and Game of Thrones’ Kit Harington.

Based on an original concept by Murray Miller, who wrote the screenplay, and Samberg, the sports mockumentary centers on two fierce tennis rivals in an epic, seven-day match at 2004 Wimbledon.

The location is hardly random — the longest tennis match on record was held on Court 18 at Wimbledon during the 2010 championships when John Isner and Nicolas Mahut battled it out for 11 hours over three days, with the American ultimately clinching a victory, 70-68 in the fifth set.

In addition to Samberg, Harington and Armisen, the all-star cast includes Lena Dunham, Will Forte, Karen Gillan, Howie Mandel, Michael Sheen, Mary Steenburgen and June Squibb. Additionally, broadcast journalist

Soledad O’Brien will appear in the HBO movie as herself.

Based on breakdowns reported by Deadline.com, Samberg’s character, named Aaron Williams, is tennis’ superstar bad boy, while Harington’s character, named Charles Poole, is channeling Andy Murray, a tennis prodigy and certified truck driver.

Adding to their rivalry is Gillan’s supermodel Lily, Charles’ childhood friend who made a sex tape with Aaron. Steenburgen plays Charles’ psychotic and controlling mother, while Forte plays a tennis historian.

Jake Szymanski is set to direct the film.
