As the Remember Years of Magic convention approaches (December 4-5, 2021), CloudsCon has announced that two guests are no longer able to attend the event due to travel restrictions between France and England. The two actors concerned are Josh Herdman (Gregory Goyle) and Louis Cordice (Blaise Zabini).
If this news will be disappointing for Harry Potter fans, the French organizer was able to rebound quickly by announcing two replacements: Sean Biggerstaff (Olivier Dubois) and Devon Murray (Seamus Finnigan). Both are guests included in the passes with extras.
During the Remember Years of Magic convention, these two guests will do, among other things, personalized videos (20€ each), photoshoots (35€ each), autographs (30€ each), one-on-one (45€ each) and meeting rooms (70€ each). If you are interested by these activities, you can buy them on the official ticketing as well as the access passes to the event.
