Harry Potter actors Natalia Tena (Tonks) and Joshua Herdman (Goyle) are set to appear at Collectormania København (Copenhagen), which will run from November 21-22, 2009. The event will take place at the Korsgadehallen venue in Denmark; more information can be found here, for those interested in attending. We will update if and when other actors choose to attend the convention.
