Changes

The First Doctor was portrayed as a cantankerous old man. Initially a somewhat dark character, he became more grandfatherly in later episodes. [[William Hartnell]]'s era introduced the most well-known of the Doctor's foes, the [[Dalek]]s.  This was the first incarnation of the Doctor to be played by two different actors, the second being Richard Hurndall, who played the First Doctor in ''The Five Doctors,'' in 1983, as William Hartnell had died in 1975.

Troughton's Doctor was an impish figure, whose gimmicks included playing the recorder. In this period, much of which is lost, the program felt the influence of [[Star Trek]] somewhat.
