As you can tell from Derrickson’s resume, he’s really into horror movies.
And that’s a good thing because there’s always the chance that not only will Doctor Strange be scarier and weirder than anything that Marvel Studios has done so far, but that it–or a sequel if it does well at the box office–could be used as a launching pad for the adventures of The Midnight Sons, characters that inhabit the darker, more supernatural corners of the Marvel Universe, like Ghost Rider (the rights have reverted back to Marvel a few years ago), Blade (ditto) and Morbius, the Living Vampire.
And before anyone rules out The Midnight Sons, keep in mind that ten years ago no one in their right mindwould think that there would ever be a movie based on Doctor Strange, Marvel’s Master of the Mystic Arts.
Though come November, there will be.
