What were those last days on set like?
“[Harry Potter] was such a massive part of my life. It really has been my life. I can’t really remember a life before it. For that to just all come down to just like, one day, and like one thing, just seems really strange. Yeah, it was emotional. There was a real sadness about it and quite an empty feeling. So, I remember packing up my room, boxing everything up and I had like, toys from when I was 10. It was weird.”

Hogwarts comes under attack. What was it like seeing those sets getting torn apart?
“That was quite strange watching this place so familiar to us that it’s almost part of like a second home. It was kind of alarming really. They were just kind of simultaneous- the film ending and the sets being destroyed. I was struck the first time I saw the Great Hall become a big pile of burning rubble and getting scattered around. It’s really quite shocking for the fans.”
