"The day we shot the scene of the death of Fred, I was aware of what was going to happen, so every time I happened to see James I became very sad. When we started to turn James was lying on the gurney, awaiting the arrival of the rest of the cast. It was enough to watch it once and I just burst into tears. I can not even imagine how I would feel if I lose him. We have done everything together since our birth and to see my brother lying on a stretcher while pretending to be dead, killed me deeply. Then, after James got up and I hug him, David said,’ You were perfect! It was really believable! ‘and I told him that I thought as if we were James and I, not Fred and George."
This is the difference between acting the part and living the part.
