‘Doctor Who’: Matt Smith and David Tennant Join Forces in 50th Anniversary Poster

Matt Smith's days as Doctor Who may be numbered -- but before he goes, he'll topline one of the biggest events in the sci-fi series' history.

The Day of the Doctor, the BBC drama's 50th anniversary special, premieres in the U.K. and the U.S. on Nov. 23. Trailers for the special have been screened at Comic-Con and for members of the press, but for the public, key art released Tuesday provides a first look at the episode.

Smith, joined by previous Doctor David Tennant look deadly serious above an image of fellow guest John Hurt emerging from an explosive collage of significant images to the show's past. And it's Hurt, as Smith recently noted, who steals most of the scenes.

"David and I would be climbing the walls, and then John just flicks his eyes and the camera goes, 'Oh yeah, let's watch John Hurt,'" Smith told reporters at July's Television Critics Association summer press tour.

Smith's Doctor Who successor was recently revealed to be The Thick of It actor Peter Capaldi. He'll take over the role at the conclusion of this year's Christmas special.
