Harry Potter actors attend SuperCon 2008
SuperCon 2008 was held over the weekend in Weston, Florida. Potter actors Natalia Tena (Tonks), Devon Murray (Seamus), Hugh Mitchell (Colin Creevey), and Danielle Tabor (Angelina Johnson in SS through POA) were all present during the event and participated in a panel discussion.
Snitch Seeker has video of their talk right here. In it, they talk about their favorite Potter characters, fan experiences, and whether or not they've read Deathly Hallows (they all say no).
