Who Shined Bright in Iron Man 3?

Understanding the Context

At the core of Iron Man 3 sits the Cassians Scott’s world—literally and figuratively. Robert Downey Jr. remains the undeniable anchor: Tony Stark’s wit, vulnerability, and complexity came to life with rare intensity. But he’s supported by a cast whose nuanced turns deserve deeper appreciation.
