"The Zapruder film is a silent 8mm color motion picture sequence shot by Abraham Zapruder with a Bell & Howell home-movie camera, as United States President John F. Kennedy's motorcade passed through Dealey Plaza in Dallas, Texas, on November 22, 1963. Unexpectedly, it captured the President's assassination."
