Earlier this year I visited a series of large buildings that stood beside a dank wood in Surrey, England. Inside was Kamar-Taj, an ancient training academy tasked with preparing the next generation of sorcerers. This is where Doctor Strange was learning his craft and becoming a Master of the Mystic Arts. Below is a collection of interesting things I learned that day, from Kevin Feige, the film's director Scott Derrickson, and Strange himself, Benedict Cumberbatch.
