Daniel Radcliffe Reveals Which ‘Harry Potter’ Star Scared Him the Most

He-Who-Must-Not-Be-Named was a scary guy.

Daniel Radcliffe recently admitted that some of his famous Harry Potter co-stars scared him. Although many believe Severus Snape, played by the late Alan Rickman, was very intimidating on-screen, the actor reveals that Ralph Fiennes’ character, Voldemort, “genuinely scared” him.

“I remember when I was 15 doing scenes with Ralph for the first time. He was even scarier than Alan was at first,” the actor, who admits he’d play Harry Potter again, told People and Entertainment Weekly editorial director Jess Cagle. “Alan was super intimidating to start off with as well, but then you get into it, but Ralph genuinely scared me for a few years.”

But, besides discussing what terrifies him, Radcliffe was also interviewed by some adorable Harry Potter fans about magic, wizards, and more. What’s the special effect that turns you invisible? How do make broomsticks fly? Were just some of the questions they had for him.

Watch Radcliffe answers all of them in the video below.
