Doctor Theatre (2020)

In "Doctor Theatre", actor Mark is seduced into joining a theatre company named Communion, only to find that it also secretly operates as a death-cult: during auditions and rehearsals for its productions, selected actors are sacrificed and then reborn into a bloodthirsty new family. By the end of season 1, horrified by the dark destiny he's fallen into but addicted to the growth of his own power, Mark has risen to become the new Director of Communion. In season 2, he tries to escape and to hide himself away from it. However, an established priest-like member of the company named Michael tracks Mark down and entices him back, to spearhead the sinister cult's transition from theatre to cinema. Mark then tries to change Communion's murderous ways from within -- but discovers its ancient powers are not so easily controlled.
