Actor, writer, and host of comedy panel game television programme QI was interviewed recently by RadioTimes about why he asked Daniel Radcliffe to participate on show as a guest panelist in the H series for the Halloween special, to air October 29, 2010.

"He's a very bright chap and he has what it takes to be a guest on QI, which is to be curious. Because if you are curious, a) you will be interested by what's coming and you fire off it and b) in the rest of your life you will have garnered odd facts. Not in a sort of anal 'I collect trivia sort of way', but just because you are curious." 

The H series of QI begins next Friday, September 17, on BBC One. Daniel's episode, the seventh in the series, will air October 29, 2010, two days before Halloween.
