It was lights, camera and action for Daniel Radcliffe and the rest of the Potter crew as they moved to Gloucester to film more scenes for the sixth film.
They were at Gloucester Cathedral for an early-morning filming session for Harry Potter and the Half-Blood Prince.
Film-makers set up tents around the cathedral - one of the settings for Hogwarts school - last month, but the scenes are only just being shot.
The Philosopher's Stone and Chamber of Secrets also used the cathedral.
It's really exciting for kids who go to the school next to the cathedral, with 174 of them appearing as "extras" in the movie.
"There's a real buzz at the school, it's a fantastic time," said a school spokesman.
Filming for the Half-Blood Prince started in September.
It's set to come out in the UK on November 21.
