I noticed that someone had recorded Jonathan Ross on The Eisner Awards At 2014 San Diego Comic Con and that lead me to this JK Rowling appearance on Friday Night with JR. It's episode S12E15 and it aired July 7 2007. That was just before the last novel came out on July 21. I found it an entertaining interview and Jonathan seems to really like the series. It reminds me I should watch the films again.
