I’m talking about character evolution, which is not unique to Iron Man (that’s why I brought up the other examples like Bale’s Batman). Craig’s Bond is clearly designed to show growth throughout the films. In CR he’s at the start of his career and is a diamond on the rough. By SP, he’s fully grown into the more sophisticated secret agent we’re familiar with in older films, casually strolling the rooftops of Mexico City before performing a hit, and when he prevents Lucia from being assassinated he acts as if it’s just a stroll through the park.
