Matt Ogen's charming documentary Confessions of a Superhero, out on DVD this month, chronicles the down-and-out lives of four aspiring actors who suit up as famous superheroes on Hollywood Boulevard to pose for photos with tourists, collect tip money, and get a big-screen break (they hope). The film is simultaneously funny, poignant, and creepy, showing the crew to be anything but the invincible heroes they portray. There's the physical: "The Hulk" passes out in a Hollywood restaurant on a 106-degree day that almost melts his plastic suit. And there's the emotional: "Superman" is a recovering addict. Here we list some of the major differences between the real people and their Hollywood Boulevard hero counterparts.
