29/09/2013 10th Doctor BFI Screening - DT explaining Big Finish to Catherine Tate!

Just a quick video from today's brilliant BFI screening of Stolen Earth & Journey's End followed by Q&A with David Tennant, Catherine Tate, Phil Collinson and Graeme Harper. I recorded just a couple of answers that I hoped would be funny including this one in which David & Catherine are asked if they'd do a Big Finish adventure and DT has to explain what Big Finish is to Catherine!
