And he admits he was reminded of his own mortality while shooting a key scene in Harry Potter and the Deathly Hallows, in which his character faces death.
He says, "I'm possibly a very morbid person, but I think about death a lot. I don't know if it's maybe from being in films, or from playing Harry, but I just think it's a natural thing that I have. It's fascinating in a very alien kind of way.
