Since its premiere in 1968, 2001: A Space Odyssey has been analysed and interpreted by multitudes of people ranging from professional movie critics to amateur writers and science fiction fans. The director of the film, Stanley Kubrick, and the writer, Arthur C. Clarke, wanted to leave the film open to philosophical and allegorical interpretation, purposely presenting the final sequences of the film without the underlying thread being apparent; a concept illustrated by the final frame of the film, which contains the image of the embryonic "Starchild".
