Marvel Studios created a shared world for its superhero films, known as the Marvel Cinematic Universe, by departing from traditional methods of translating comics to the big screen. Unlike prior efforts, Marvel Studios developed an ambitious plan to set its films within a single, interconnected narrative environment.12

This strategy involved producing individual blockbuster films for specific heroes—such as Iron Man, Thor, and Captain America—and subsequently uniting them in a crossover film, The Avengers (2012). This approach allowed the franchise to build a cohesive setting that could incorporate both established icons and relatively unknown characters, such as the Guardians of the Galaxy, Ant-Man, and Doctor Strange. The success of this model eventually expanded to include television programs and strategic collaborations, such as the 2015 agreement with Sony to integrate Spider-Man into the shared universe.12
