Jo Martin

Jo Martin (born 29 April ) played the Fugitive Doctor in the Doctor Who television stories Fugitive of the Judoon, The Timeless Children and Once, Upon Time. alongside Jodie Whittaker's Thirteenth Doctor. She had also portrayed Ruth Clayton, a disguised version of the Fugitive Doctor, in Fugitive of the Judoon.

She was the second non-white actor to be cast in the role of the Doctor in the DWU and the first to be explicitly portrayed as the Doctor; Steven Moffat stated in a 2008 email exchange with Russell T Davies that Doctor Moon, played by Anglo-Jamaican actor Colin Salmon, was similarly intended to be a future incarnation of the Doctor, but this goes unstated in Silence in the Library/Forest of the Dead. (REF: Showrunner Showdown)

In an interview with DWM 549, Martin mentioned that she had watched the show as a child, and had always wanted a part in it.

Career
At the time of her Doctor Who appearance, Martin was perhaps better known as Max McGerry in the hospital drama series Holby City (1999–2022).
