By now, you know (and have probably seen) Doctor Strange, the 14th entry in the Marvel Cinematic Universe. But did you know that attempts to make a movie about Doctor Strange date back decades before Iron Man? In 1978, they even made a Doctor Strange TV movie, in an attempt to recreate the successful formula behind the popular Incredible Hulk TV show. That’s just one of the “strange” facts featured in the newest episode of You Think You Know Movies!

After years of stops and starts, the Doctor Strange movie finally came to theaters this fall under the direction of Scott Derrickson. (The list of other directors who tried to make a Strange film include Wes Craven.) To convince Marvel that he was right guy for the job, Derrickson wrote a 12-page treatment, made a series of storyboards, created his own concept art, and even his own digital animatic for some of his proposed special effects, which he pitched to studio executives as part of a 90-minute meeting. The animatic cost Derrickson an “obscene” amount of money, but it was worth it; he ultimately got the gig.
