After the success of Back to the Future, Robert Zemeckis and Bob Gale worked on the problem of a sequel. In the theatrical release, the departure of Doc, Marty and Jennifer was followed immediately by the credits. When the film was released on VHS and Laser Disc on November 30, 1986, "To Be Continued..." was added. Out of place in 1967, Marty ends up in jail. Lorraine posts his $500 bond and cancels her plans for a romantic weekend with George in San Francisco. Marty realizes that his birthdate is nine months away and that he has, once again, endangered his existence.
