Well, that was quick: The BBC will reveal the 12th Doctor in a live special this Sunday. The special will air in the U.K. on BBC One at 7p.m., and on BBC America at 2p.m. Eastern. There will be guests including “Doctors old and new” as well as reigning Doctor Matt Smith and executive producer Steven Moffat.
Smith, who’s starred in the show since 2010, has two specials before he hangs up his bow tie for good: The 50th Anniversary special (with the 10th Doctor, David Tennant) in November and the Christmas Special, where he will regenerate into the new actor or actress. The new Doctor will go on to star in the eighth series with current companion Jenna-Louise Coleman.
