The eight installments of the "Harry Potter" series will be screened during the Shanghai film festival, announced the organizers last weekend. It was also revealed that J.K. Rowling, the writer of the book series as well as the script writer and producer for the film series, will present a big surprise to Chinese fans.

The mystery can only be solved at the Shanghai theaters in June.

It is unknown if the surprise is linked to "Fantastic Beasts and Where to Find Them," the first installment of a film trilogy written by J. K. Rowling directed by David Yates, a spin-off of the Harry Potter film series to be released on Nov 18, 2016, or the two-part London West End stage play "Harry Potter and the Cursed Child," which is set to open on July 30, 2016.

The 19th Shanghai International Film Festival will be held from June 11 to 19, 2016. In addition to the Pixar selection, there will also be several special screening selections this year, including Tribute to Masters, Classic 007 Films Screening, Oscar Film Panorama, Jackie Chan Action Movie Week, New Works of Renowned Japanese Directors, Korean Films, Retrospective of Recent Works of Woody Allen, 4K Restored Classic Film Panorama and others.

Ticket sales will start at 8:00 am on June 4.
