So apparently despite Benson and Moorhead because being announced last year as the directors/creators for Moon Knight, it looks like they just directed two eps, ep2 & ep4. They didn't create the series, they don't have producer credit and they don't have any credit at all on ep1.
But also apparently whatever happened wasn't a fallout between them and Marvel because the article I found on this says they were then hired to direct Loki S2. I feel like they're not going to get a lot of creative control there though. Still, I guess they're developing a good working relationship with Marvel. I wonder if having Anthony Mackie as their lead in their last film before these opened the door to getting them into the MCU director group. Pretty sure they are glad to be making $$$ since their indie stuff, while great, probably didn't make much.
