The Marvel Cinematic Universe (MCU) is the most successful franchise in movie history. So far, Marvel Studios (a subsidiary of Disney) has produced 29 titles—from Iron Man in 2008 to Thor: Love and Thunder this year. Collectively, the movies have grossed over $26 billion worldwide. That’s before factoring in the TV shows, video games, theme park rides, merchandise, and all the other movies scheduled for production in years to come. These films have caused a cultural and economic sensation that merits more than passing attention.
