The Harry Potter and the Philosopher's Stone movie is set to smash UK cinema records.
So many people are desperate to see the film that hundreds of thousands of tickets have been sold already.
So many that the film has sold the most advance tickets ever for a film in Britain.
Warner Village cinemas have sold 140,000 tickets, UCI Cinemas 120,000, and the Odeon chain has sold 200,000 tickets, worth more than a £1m in total.
Lots of tickets left
The Odeon chain has 599 screens in Britain, and Harry Potter will be showing on almost half them following its release on 16 November.
However cinema bosses were quick to point out that there were still plenty of tickets left to see the film.
