In the dying months of 2010, on a sound stage at Pinewood Studios, the boy who was Harry Potter is in the process of proving he has more to offer. There are two sides to Daniel Radcliffe on the set of this new film. The first is in front of the camera: pensive, still, silent. Radcliffe’s Arthur is a desperate man, still beside himself with grief at the loss of his wife, adrift in a creepy village itself all too familiar with death. Off screen, he is alive; high on the atmosphere of the set, to be found gossiping with the crew or reading aloud from a copy of The Timewaster Letters, Robert Popper’s zany correspondence with ever-patient department stores and industry associations. For Radcliffe, the attitude is as important as the acting. “I’ve seen film sets where the actors are playing up and they’re miserable,” he says. “I think you have a responsibility, as a lead actor, to be leading with energy as much as you can. I love my job and, generally speaking, I’m always happy on set.”
