With Iron Man an immediate blockbuster, it's appropriate that the Metropolitan Museum of Art's star-filled Costume Institute gala--and, more important, the accompanying exhibit--celebrated superheroes. Having written for The Atlantic on fashion in art museums and the glamour of superheroes, I made a side trip from Washington to New York for the press preview. I wrote a short item about the exhibit and also narrated a slide show. (Thanks to my colleague Jennie Rothenberg Gritz, who produced the slide show.)
