Still, the conventions try to attract the fandom with other fun-filled "Potter"-centric activities, often more interactive, such as wizarding chess, water Quidditch, a showing of the "Harry Potter" films, or local cultural immersions. Live podcasts are often recorded during these events, and live Wizard Rock shows have become a fairly large part of recent conventions. Members of the "Harry Potter" cast have been brought in for the conferences; actors such as Evanna Lynch (Luna Lovegood) and Christopher Rankin (Percy Weasley), along with several others, have appeared to give live Q&A sessions and keynote presentations about the series.
