"House of the Dragon" showrunner quits after HBO denies wife's producer job.
Miguel Sapochnik wanted his wife, Alexis Raben, to continue on as producer for season 2.
HBO said Raben lacked the necessary experience, and a mediator was brought in to resolve the issue.
Sapochnik ultimately left the show, fired agents at WME, and moved to CAA with Raben.
Alan Taylor, "Game of Thrones" alum, joins "House of the Dragon" as director and producer.
Season 2 is expected to focus on Dance of the Dragons and introduce characters like Cregan Stark.
It will also explore Rhaenyra Targaryen's reaction to her son's death.
The season 2 timeline may slow down significantly compared to season 1.
Sapochnik's departure's impact on the show is not yet known.
"House of the Dragon" season 2 is set to premiere in 2024.
