Amicus Productions
In the mid-1960s Amicus also produced two films based on the television series "Doctor Who" which had debuted on television in 1963. The films, "Dr. Who and the Daleks" (1965) and "Daleks' Invasion Earth 2150 A.D." (1966), are the only theatrical film adaptations of the series. In these films Peter Cushing played "Dr. Who", a human scientist rather than an alien, with "Who" as his actual surname, ignoring the backstory of the TV series.
