“We properly met on the set of Harry Potter and the Half-Blood Prince, in full costume. Helen with that white stripe in her hair, me with those black buttons and black contacts. Helena was there too. We had a scene with the three of us, nose to nose, having to look threateningly at each other. Helen has a huge sense of the ridiculous and with all that costume and make-up, there wasn’t a hope: we were all trying to behave like grown-ups but laughing to an annoying degree; the producers and crew got a little impatient. It’s run like an army camp there, so I was grateful for those moments of laughter.” - Alan Rickman about how he met Helen McCrory
