Black Panther hits theaters everywhere tomorrow. The buzz around the movie is electric, as evidenced by its formidable social media presence, record-breaking box office projections and ubiquity in the thinkpiece realm. Though the reviews are glowing, what seems to be propelling this global phenomenon is not the movie itself, but its materiality to the world as it is today. In the comic book world, the word “retcon” is a common portmanteau for “retroactive continuity.” It refers to the reframing of past events to serve a current plot need. For example, TV shows often retcon characters’ backstories in order to explain their present actions.
