The King's School is next door to the famous Gloucester Cathedral, whose cloisters have been used for Hogwarts corridors in both movies.

CBBC Newsround has discovered that it's meant that school has seen the number of applications grow by a record level in the past year.
Even though most of the extras only saw themselves for a few seconds, but that was enough to make mates jealous!
