During his time on Doctor Who (1963) he began to increasingly suffer from arteriosclerosis, which caused him to often make mistakes while delivering his lines. Due to lack of time and money, scenes were usually filmed using one take, so these mistakes ended up in the finished episodes and are considered among fans to be something of a trademark of Hartnell's performance as the Doctor.

In 1966, due to the actor's health problems, the decision was made to replace Hartnell as the Doctor but continue the series. The story editor of Doctor Who (1963), Gerry Davis, came up with a unique idea: since the Doctor is an alien, he can transform into another man when he dies, thereby renewing himself. Hartnell reportedly approved of the casting of the versatile character actor Patrick Troughton to succeed him, a decision by Innes Lloyd, the then producer of the series. However, his former co-star Peter Purves stated in an interview that Hartnell would almost certainly have felt very hurt that anybody felt he could be replaced in the series because he had become so attached to the part that he had originated.

His was the only version of The Doctor who smoked (In his case, a pipe).

He first took the role of the Doctor to get away from being typecast as gruff military types and to appear in something his grandchildren could watch.

He appeared in 134 episodes during his three years on Doctor Who (1963). This was eventually overtaken by the Fourth Doctor, Tom Baker, who appeared in 172 episodes over seven years. This heavy workload became tough for Hartnell as time went on and his health began to decline.

I don't like anything blue or salacious or suggestive because I'm not that type of actor.

[on children] They find me a cross between the Wizard of Oz and Father Christmas.

I'm a legitimate character actor of the theatre and film.

[on the Daleks] They were difficult to play to. Because you're not looking into human eyes, you know what I mean. You're looking at a metal object moving about, with a voice-over.

Space travel? Quite honestly, it scares me to death. I haven't the slightest wish to get in a rocket and zoom through the stratosphere. Somebody else can be the first man on the moon. It doesn't interest me at all. I do, however, believe that there is life on other planets - and that they know we're here but haven't got the technology to get through.
