What was the most challenging thing to film physically and emotionally [in Deathly Hallows]?
Dan: Physically? Well, underwater stuff is always pretty tricky. In this case it was particularly tricky because it’s a big fight scene. I’m going under into the frozen lake to get the sword of Gryffindor and obviously the horcrux is fighting for its existence and is trying to kill me. We do what will hopefully be a pretty terrifying almost semi-homage to The Omen where I get dragged up against the ice and toyed around by the locket. So that was pretty challenging.
