A popular variety TV show called Sanma no Karakuri TV had a contest where 10,000 Japanese Harry Potter fans competed for a chance to fly to the UK, visit the set of the HP movies, and interview Ron and Harry. The winner was a high school girl named Kana Matsuda. Here’s a hilarious clip of her interviewing Rupert Grint, who plays Ron Weasley. Watch it! It has subtitles. I’m personally a bigger fan of Ron than Harry, but if you want to watch the video of her interviewing Daniel Radcliffe, it’s here.
I just watched Harry Potter and the Half-Blood Prince at the theater on Friday 2019, btw. It was fun!
