Mare of Easttown ended in May 2021, but its legacy will reportedly live on in Mark Ruffalo's upcoming television series, Task, which must take advantage of its connection to the critically acclaimed show starring Kate Winslet. The 2021 crime drama limited series was created and written by Brad Ingelsby for HBO, and Ingelsby is also the mind behind Ruffalo's new show alongside Jeremiah Zagar. Following the success of Mare of Easttown, Ingelsby secured a three-year deal with HBO to create new projects for the premium cable network, leading to the development of Task, which doesn't have a premiere date yet.
