Catch an extended clip of the new series and a panel discussion with actors John Barrowman (Captain Jack Harkness); Eve Myles (Gwen Cooper); series writer Chris Chibnall; and executive producer Julie Gardner. TV Guide's West Coast Bureau Chief Craig Tomashoff moderates. Room 6A
However, it has been confirmed by the webmaster of his official site that John Barrowman will not be in attendance, due to work commitments in the UK.
