“Everyone’s got their own continuity wand, even down to the Death Eaters,” Wilkinson said. “All the principal characters have their own wands, and they’re all listed and accounted for, and it’s an amazing system. And each wand is individual. It’s an incredible job just designing those and to keep trying to think up different designs for wands, but when you look at them, they are just totally different.”

“Each one’s got a number, and it’s checked out and it’s checked in at the end of each day,” Wilkinson said. “We have some broken, but they’re all accounted for, and we have to make notes of and keep records of everything.”

“At the moment, we’ve got 104 containers full of props and set dressings, which have now got to be lifted and archived and accounted for.” For Wilkinson, who’s become accustomed to breaks of less than 10 weeks between films, the movies seem like one massive undertaking rather than individual projects.

“We’ve worked on them for so long, it’s very hard now just to decipher from one film to the next, and it all blends in as one huge project,” he said. “It’s a shame. We wish they could go on again, but it’s been a real marvelous achievement and a marvelous project to work on, you know? Myself and all my team are really proud to have worked on it.”
