Actor David Thewlis is forced to hand his props back to security staff on the set of HARRY POTTER AND THE HALF-BLOOD PRINCE - in case they missing.
The British star, who plays Remus Lupin in the hit wizard franchise, reveals security is so tight that the film's cast have to give back their props as soon as the cameras stop rolling.
Thewlis says, "You finish a scene and the crew treat your wand like it was a diamond and take it straight off you. Filming hasn't even finished and there is already a big fight for the props."
