Task: cast, plot and everything we know about the Mark Ruffalo crime drama
Mare of Easttown creator returns with a brand new crime drama for TV fans to become obsessed with.

One of the most talked-about shows of 2021 was the crime drama Mare of Easttown, which starred Kate Winslet as a cop in a Philadelphia suburb dealing with investigating the murder of a teen mother and the struggles of her own family. Well, Mare of Easttown creator, Brad Ingelsby, has a brand new crime drama that may very well become your next TV obsession in Task.
There’s a good deal that is similar between Task and Mare of Easttown— an A-list star (in this case Mark Ruffalo), the setting in another Philadelphia suburb and being an HBO project — but there will be plenty new to the series, from a cast of young actors landing big roles to a bonafide antagonist behind the string of crimes at the center of the story.

Task release date
We don’t have an exact release date for Task at this time, but HBO has confirmed that the show will premiere in September on HBO, streaming simultaneously on HBO Max (the name change from the currently branded Max will have taken place by then).
There was no indication on what night Task would air, but given that Sunday nights are HBO’s usual slot for major TV shows, we’d guess that to be the slot for Task. If that proves true, the possible premiere dates for Task would be September 7, September 14, September 21 or September 28. When HBO confirms the official release date, we’ll update this post.
To watch Task on HBO, you’ll need a pay-TV provider that carries the premium cable channel or a subscription to Max/HBO Max.
Right now, we don’t have any information on when Task may premiere in the UK, though HBO series usually air on Sky Atlantic and NOW TV around the same time as their US premiere.
