William Hartnell(1908-1975)

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.

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