Robert Downey Jr.

Iron Man, starring Robert Downey, Jr. as the armored superhero, enjoyed a $100 million dollar opening weekend.

Comic-book fanboys should rejoice at this weekend's box office numbers, while moviegoers who either dislike superhero flicks outright or (like yours truly) enjoy them only in limited doses should be wringing their hands over Iron Man's haul. Coming at the beginning of a summer already glutted with superhero fare of various sorts, the film's success promises to cement the comic-book movie's Hollywood hegemony for years if not decades to come.
