Iron Man

To become a mega-movie star these days, a man must don the tights. With a few notable exceptions like Leonardo DiCaprio, who had the good fortune to be in the highest-grossing movie of all time (that would be “Titanic”), almost every $20 million man has done his time as a caped crusader, masked marvel or some popcorn equivalent, such as a pirate or extraterrestrial G-man.
