Robert Pavey
From Tardis Wiki, the free Doctor Who reference
Robert Pavey was a stunt performer credited on the Doctor Who television stories Deep Breath, Robot of Sherwood, Listen, Flatline, Death in Heaven and Resolution, and on the Class television story The Lost.
Outside the DWU, he's worked on Game of Thrones, Guardians of the Galaxy, Sherlock, Thor, Holby City, Hollyoaks, Casualty, Coronation Street, Beowulf and Emmerdale.
He is also a member of a jousting stunt team called the Knights of the Damned, and, as such, he specialises in horse-riding. Two of his three Doctor Who stories involve characters on horses at one point or another. He likely doubled for Peter Capaldi for some riding scenes in Deep Breath.
