Where to view deleted scenes[]

    • 1955 Doc looks at his personal belongings from 1985.
    • In 1985-A, Marty sees a burned-out Hill Valley High School.
    • Old Biff fading out of existence in 2015.

Later releases removed the scene.
  • The scene where Marty exits through the window of his room was filmed and the bloopers of that scene can be found online in a compilation of other bloopers.
