Harry Potter stars joined author J.K. Rowling at the Studio Tour over the weekend to raise money for the Lumos Foundation.

According to a statement from Rowling’s camp, the event had lots of fun activities for wizards of all ages. The Harry Potter Studio Tour was “made exclusively available by Warner Bros. for the special event. Guests were invited, with their children, to join J.K. Rowling and celebrity guests, to enjoy a visit to the Studio Tour, followed by a dinner and charity auction for the adults in the Hogwarts Great Hall. Younger guests were entertained by magicians, entertainers and the animal actors from the Harry Potter films.”

Potter film stars Alan Rickman (Snape), Emma Watson (Hermione), Evanna Lynch (Luna), and Warwick Davis (Flitwick/Griphook) were in attendance.

On Sunday, Rowling took to her Twitter to announce that over £1 million was raised.

Lumos’ funding and teams go to projects in Bulgaria, the Czech Republic, Ukraine and the Republic of Moldova. All aim to help “reunite children with their families or [put them] into family-based care, reforming the care system and developing community-based and specialist services for future generations of disadvantaged children,” according to the Studio Tour fundraiser statement.

On Saturday Watson posted a photo of herself posing with a dummy version of Hermione used in Goblet of Fire. She hilariously posed liked the dummy…

Congratulations to Rowling, the Lumos Foundation, and the Harry Potter cast on a very successful fundraiser!
