Behind the scenes of "42". It's back into outer space for Doctor Who and this time it's an adventure set entirely on a spaceship. Join Confidential as we gain exclusive access to Doctor Who's art department and take you on a tour of the spaceship's sets and locations. Confidential also journeys back in time to show you some of the best off the wall spaceship designs seen in five decades. Guest star Michelle Collins discusses her role as the ship's captain, and how she felt performing stunts on her very first day on set. From models on wires to cutting edge CGI, this is a space craft extravaganza. (thetvdb.com)
