Daniel Radcliffe was 11 years old when he answered a call to audition for a movie based on the wildly successful Harry Potter books. By the next year, he was the most famous 12-year-old on earth. That first movie made a billion dollars at the box office, setting off a worldwide craze that led to seven more films with Radcliffe starring as Harry. He came out the other side of that 10-year run intact, at just 22 years old, and with the freedom, earned from the success of Harry Potter, to take on only the projects that strike him, like his latest, playing Weird Al Yankovic. Willie Geist got together with the actor in New York City as Radcliffe prepares for his next role, starring in a Stephen Sondheim musical.
