In the final moments of 2008’s Iron Man, after the climactic battle and as the credits begin to roll, a scene unfolds that would prove more revolutionary than any of the film’s impressive special effects. In the shadows of Tony Stark’s Malibu mansion, a mysterious figure appears. “You think you’re the only superhero in the world?” he asks, introducing himself as Nick Fury, director of S.H.I.E.L.D. “I’m here to talk to you about the Avenger Initiative.” This quiet yet audacious moment promised a “bigger universe” that no studio had ever successfully delivered on screen. At a time defined by self-contained trilogies and standalone reboots, this post-credits scene was not just a sequel hook; it was the cornerstone for a new kind of cinematic mythology.
