Fan site MuggleNet will host MuggleNet Live! 2015: Expo Patronum this Saturday - focusing on everything to do with our favourite wizard.

Visitors will be able to meet stars of the movies, the crew, and plenty of special guests from the Harry Potter world, including Alfred Enoch, who played Gryffindor Dean Thomas, Afshan Azad who portrayed Hogwarts student Padma Patil, art director for the whole series Gary Tomkins and fantasy favourite Warwick Davis.

A spokeswoman for MuggleNet said: “At the event you will be able to participate in Q&As with the actors from the films as well as secure their autographs and join them in the photo booth.

“Guests will also be able to discover creative secrets from the films’ graphic designers, MinaLima, and art director, Gary Tomkins, and learn wand movements from the series’ choreographer, Paul Harris. And for those who upgrade for the Signature Experience, you will enjoy an exclusive VIP experience where you will be able to interact with the guests in a more informal setting.”

“We have hosted live podcasts over the years and joined panels at other conventions, but this is the first of this kind of event for us. After 15 years online, we thought it was about time”.

April 18, 10am, Excel Centre, Royal Victoria Dock, £45-100, live.mugglenet.com .
