Daleks' Invasion Earth 2150 A.D. Daleks' Invasion Earth 2150 A.D. Daleks' Invasion Earth 2150 A.D. is a 1966 British science fiction film directed by Gordon Flemyng and written by Milton Subotsky, and the second of two films based on the British science-fiction television series "Doctor Who". It stars Peter Cushing in a return to the role of the eccentric inventor and time traveller Dr. Who, Roberta Tovey as Susan, Jill Curzon as Louise and Bernard Cribbins as Tom Campbell. It is the sequel to "Dr. Who and the Daleks" (1965). The story is based on the "Doctor Who" television serial "The Dalek Invasion of Earth"
Doctor Who and the Silurians Carey Blyton, who would also contribute music for "Death to the Daleks" (1974) and "Revenge of the Cybermen" (1975). This story is the first to be recorded using colour studio cameras. The previous serial, "Spearhead from Space", was the first in colour, but was shot entirely on location (i.e., outside the electronic TV studio), and on film (as opposed to videotape, the standard method for recording "Doctor Who"). Due to the move to colour, the production team made use of a technique known as Colour Separation Overlay (CSO, or Chroma key), which allowed images to be superimposed over each other
