8 Actors Who Appeared as Different Characters in Doctor Who and its Spin-Offs
The most obvious example. Before becoming the Twelfth Doctor, Capaldi put in a memorable performance as John Forbisher in Torwchood: Children of Earth.
Miller, who was married to Elisabeth Sladen before her untimely death, appeared in Doctor Who three times, playing Dugdale in ‘Snakedance’, voicing Daleks in ‘Resurrection of the Daleks’, and playing Barney in ‘Deep Breath’. In between the last two he appeared alongside his late wife as Harry in The Sarah Jane Adventures.
Myles popped up as Gwyneth in ‘The Unquiet Dead’ before joining Torchwood as Gwen Cooper.
Armstrong voiced Mr Smith, Sarah Jane’s helpful supercomputer in all five series of The Sarah Jane Adventures before appearing as Reg Arwell in ‘The Doctor, the Widow and the Wardrobe’.
After playing the Mona Lisa (yes, that Mona Lisa) on The Sarah Jane Adventures, Jones gave a face and a voice to the TARDIS in ‘The Doctor’s Wife’.
Sumpter has had multiple on Doctor Who, the most notable being Rassilon in ‘Hell Bent’. Before that he appeared on The Sarah Jane Adventures as Erasmus Darkening in ‘The Eternity Trap’.
Quesnel captained Amy and Rory’s almost doomed honeymoon cruise in ‘A Christmas Carol’ and can now be seen on Class as Coal Hill’s new head teacher.
Before he appeared in Torchwood as the dying Henry Parker, Briers gave an infamously bad performance as the Chief Caretaker in ‘Paradise Towers’.
Ben Miller is set to guest star opposite Peter Capaldi when the new series of Doctor Who returns this autumn.
Commenting on his role, Ben Miller said: ‘As a committed Whovian I cannot believe my luck in joining the Twelfth Doctor for one of his inaugural adventures. My only worry is that they’ll make me leave the set when I’m not filming.’
Miller achieved fame as half of comedy duo Armstrong and Miller before success in dramas, including Primeval and more recently, as DI Richard Poole, the central character in the first two series of the BBC’s Death in Paradise.
Miller’s partner in comedy, Alexander Armstrong, appeared in Doctor Who’s 2011 Christmas Special, playing Reg Arwell, but it’s Miller’s first time on the show and he’ll be starring in an episode written by Mark Gatiss.
Steven Moffat, lead writer and executive producer, added: ‘Mark Gatiss has written us a storming villain for his new episode, and with Capaldi in the TARDIS, we knew we needed somebody special to send everybody behind the sofa. And quite frankly, it’s about time Ben Miller was in Doctor Who!’
