Wil Wheaton recently interviewed current Doctor Who stars Peter Capaldi and Jenna Coleman in advance of the show's upcoming ninth season (Sept. 19) and a special 3D in-cinema event (Sept. 15 and 16), and -- in an outtake from the interview released by the BBC -- he tried his best to convince Capaldi to reveal how he operates the TARDIS. Capaldi countered by asking Wheaton how he operated the Enterprise as Wesley on Star Trek: The Next Generation. Wheaton complied, hoping that Capaldi would then divulge the secrets of driving the TARDIS. Did it work? Check out the video to find out.
