Director Scott Derrickson and Marvel Studios have parted ways on Doctor Strange in the Multiverse of Madness. Derrickson cited “creative differences” as the cause of his departure. He will remain attached to the film as an executive producer.

Derrickson shared the news on Twitter.

Marvel had the exact same take on the situation. “Marvel Studios and Scott Derrickson have amicably parted ways on Doctor Strange in the Multiverse of Madness due to creative differences,” the studio told Variety. “We remain grateful to Scott for his contributions to the MCU.”

Variety also reports that the Doctor Strange sequel will not be delayed as a result of Derrickson’s departure. Marvel will work to find a new director in time for a May 2020 production start and May 2021 theatrical release.
