Doctor Who "Spearhead from Space", released in July 2013 and the 1996 TV film "Doctor Who" released in September 2016. Many early releases have been re-released as special editions, with more bonus features. There are two "Doctor Who" feature films: "Dr. Who and the Daleks", released in 1965 and "Daleks' Invasion Earth 2150 A.D." in 1966. Both are retellings of existing television stories (specifically, the first two Dalek serials, "The Daleks" and "The Dalek Invasion of Earth" respectively) with a larger budget and alterations to the series concept. In these films, Peter Cushing plays a human scientist named "Dr. Who", who travels
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
