Warner Bros. Studio Tour London: The Making of Harry Potter opens at the very end of this month (March 31st) to be exact, and today fans are being given the opportunity to attend the star-studded Grand Opening!

To enter, simply head over to this site.

If you already have a ticket to visit the Studio Tour on March 31st “you will also be allowed to stay and watch arrivals on the red carpet for our Grand Opening event.”

We visited the Studio Tour last summer while it was still under construction; read our preview here!

The contest is only open to UK residents.
