Marvel's Doctor Strange director Scott Derrickson has left Twitter, and the firing of James Gunn might have been the final straw.
Website comicbook.com reports that Derrickson isn't abandoning social media as a whole though, as he will still be on Instagram. It was on that account that he posted an image of the Doctor Strange cast with a story about how the image came about.
Derrickson recently shared the Guardians of the Galaxy cast's signed statement about the firing of James Gunn. He didn't add a caption, but it seems he does support the cast in their stance.
