Doctor Who [SEP] Introduction
Beginning with William Hartnell, thirteen actors have headlined the series as the Doctor, and in 2017 Jodie Whittaker became the first woman to play the role. The transition from one actor to another is written into the plot of the show with the concept of regeneration into a new incarnation, a plot device in which a Time Lord "transforms" into a new body when the current one is too badly harmed to heal normally. Each actor's portrayal is unique, but all represent stages in the life of the same character, and together, they form a single lifetime with a single narrative.
