When it became clear that failing health was affecting his performance and relationship with the cast and crew, William Hartnell, the first actor to play the Doctor, was asked to leave the show. Hartnell had a very strained relationship with his second producer, John Wiles, and shortly after Innes Lloyd became the third producer, Lloyd told Hartnell that he was going to be replaced. Rather than cancel a successful series, story editor Gerry Davis came up with the Doctor's ability to regenerate his body when he is near death, which allows for the smooth transition from one actor to another playing the role, although this was not called "regeneration" in the series at the time. The previous production team of Wiles and Donald Tosh had considered replacing Hartnell with an actor who would play the part exactly the same as Hartnell, but Innes Lloyd and Gerry Davis preferred the idea the Doctor would become a completely different persona. The term "regenerating" was not introduced until the end of the Third Doctor's era in "Planet of the Spiders".
