Trauma counselor helps Dan play Harry

Right at the beginning, you always have these rehearsals with any actor you work with. With Dan, in particular, who had to go through this quite complex journey. We sat down several months before we started shooting. We would meet every week and we would talk about what Harry was dealing with. One of the things we did, and it sounds quite intense for a family film, is we brought in a bereavement counselor to talk to us about how Harry Potter dealt with witnessing the death of Cedric [Diggory]. This woman came in to talk to both of us about how people deal with quite intense emotional and disturbing experiences. She deals with people in the police and the rescue services who every day witnessed trauma and death, and she kind of showed us how people process that and deal with that and what it does to them.
