Oliver Phelps could only do around five takes of Fred's death scene. Seeing his brother lying there pretending to be dead was emotionally exhausting for him.
"On the day we filmed I knew it was gonna happen so every time I saw James I would get really sad. When we went to film it they had James lay down on the stretcher and just wait until the rest of the cast got there. I took one look at James on the stretcher and burst into tears. I couldn't even imagine how it would feel to lose him. We have done everything together since birth and to see my brother laying down on a stretcher pretending to be dead just killed me inside."
