For years now, pundits have been declaring that movie stardom is dead. Everyone from Jennifer Aniston to The New York Times seems to have agreed that we simply don’t make ’em like we used to.

When people talk about “movie stars” — as opposed to just anyone who stars in a movie — they specifically mean those rare individuals gifted with so much on-screen charm and charisma that they’re impossible to look away from.

Iron Man in 2008, and his recurring role as Tony Stark in the Marvel Cinematic Universe movies that followed, launched RDJ’s career into the stratosphere and made him a superstar. He’s the only one who got that level of fame boost from the Marvel machine, though. And getting there required him to........
