Andy Samberg and Murray Miller are developing a follow-up to their comedy special “7 Days in Hell” for HBO. “Tour de Pharmacy,” a sports mockumentary, will take a look at the rampant doping in the world of professional cycling. Samberg and Miller will executive produce the special through their company Legends of Sport.

David Bernad will also executive produce with M Elizabeth Hughes producing. Jake Szymanski will direct and co-executive produce. Samberg is set to star alongside Daveed Diggs, Julia Ormond, Phylicia Rashad, Will Forte, Dolph Lundgren, John Cena, Mike Tyson and Nathan Fielder.

Samberg and Murray’s first collaboration, “7 Days in Hell,” premiered last year on HBO. The 45-minute mockumentary starred Samberg and Kit Harrington as rival tennis players engaged in an epic seven-day final match at Wimbledon.

Miller, who serves as an executive producer for HBO’s “Girls,” is represented by UTA and Rohner, Walerstein & Miloknay. Samberg can currently be seen in the feature film “Popstar: Never Stop Never Stopping.” The fourth season of his comedy series “Brooklyn Nine-Nine” is set to premiere this fall on Fox. He is represented by UTA, Rise Management and Ziffren Brittenham.
