The J.K. Rowling PotterCast Interview is an interview with the creator of the Harry Potter series on the official podcast from The Leaky Cauldron website. Split over two episodes, PotterCast 130 and PotterCast 131, the show is hosted by Melissa Anelli (Webmistress of The Leaky Cauldron), John Noe (Creative director for The Leaky Cauldron websites), and Sue Upton (Senior news editor for The Leaky Cauldron). Like many other interviews with Rowling, she reveals several new pieces of Canon information. The Interview was later re-released as one episode, PotterCast 265
