Doctor Who (Original Series) Second Doctor 3 Series 23 Serials 118 Episodes Rated: PG
The Second Doctor was portrayed by Patrick Troughton, whose serials were more action-oriented than those of his predecessor. Additionally, after The Highlanders, stories moved away from the purely historical ones that featured during William Hartnell's tenure; instead, any historical tales also included a science fiction element. Patrick Troughton retained the role until the last episode of The War Games when members of the Doctor's race, the Time Lords, put him on trial for breaking the laws of time. The Doctor was forced to regenerate and thereafter exiled on Earth.
