It was really my first scene, and then we came into the studio and we went straight into the courtyard set for a rehearsal and Ralph was there. It was the first I’d spoken to him, but he put me at ease anyway very quickly. We had a good time at rehearsing, then we went back inside to all the hair and make up, all the blood and the bruising and the ripped clothes. We went back outside to the courtyard and it was just so different from to what we’d just rehearsed on hours before. It was really daunting at first. I mean, there was fire blazing, there was the bodies of students just laid across the courtyard.- Matthew Lewis
