Complete cast breakdown of HBO's Task: Who plays whom and where you've seen them before

Task is a forthcoming HBO crime-drama miniseries created and written by Brad Ingelsby. The series is directed by Jeremiah Zagar and Salli Richardson-Whitfield, both of whom also serve as executive producers.

The show explores moral conflict and familial friction in a blue-collar setting. It draws inspiration from Ingelsby's own experiences, including his uncle's former role as a priest and real-world FBI findings, grounded in the brutal realism of Pennsylvania life. HBO and Max will broadcast the seven episodes of the show, which will premiere in the United States in September 2025. 

The main character of Task is Tom Brandis (Mark Ruffalo), an FBI agent who was formerly a priest and is now entrusted with heading a special squad to stop a series of brutal drug-house break-ins. His main suspect is Robbie Prendergrast (Tom Pelphrey), an apparently normal garbage man whose dual identity as the thief gradually comes to light, exposing layers of stress and mental anguish.

The show was largely filmed in Delaware County and the Philadelphia suburbs of Pennsylvania, with principal photography kicking off in March 2024. By filming scenes at Lefty's Bar, which is located at 15 Strode Avenue in Coatesville and Roxborough, Philadelphia, the producers were able to portray the local atmosphere.
