Yeah, I'm curious how they'll handle him for a contemporary audience. In the 70's he was intentionally made to be trippy and they were dropping references to Tom Wolfe; the Merry Pranksters were said to be reading Dr. Strange, and it was popular among college students for it's cosmic, "out there" stories.
It's also the first truly arcane movie for the Marvel cineverse. Everything else has been science fiction, along with Thor as member of alien species. I think they could do a cool occult tie-in with Hydra and Captain America films to make it work...eager to see.
