Emma Corrin cast as lead in Brit Marling and Zal Batmanglij's new limited series.

'The Crown' actress Emma Corrin has been cast as the lead in 'The OA' creators Brit Marling and Zal Batmanglij's next series, 'Retreat' - in which Corrin will play amateur sleuth Darby Hart investigating a murder mystery set at a secluded retreat.

According to Deadline: "Retreat is a radical conceptualization of the whodunit with a new kind of detective at the helm — a gen Z amateur sleuth named Darby Hart (Corrin). Darby and 11 other guests are invited by a reclusive billionaire to participate in a Retreat at a remote and dazzling location. When one of the other guests is found dead, Darby must fight to prove it was murder against a tide of competing interests and before the killer takes another life."

Marling and Batmanglij will write and direct the limited series for FX.

In the meantime, you can rewatch 'The OA' on Netflix...
