Back to the Future Part II is a 1989 American
science fiction adventure comedy film directed by Robert Zemeckis and
written by Bob Gale. It is the sequel to the 1985 film Back to the
Future and the second installment in the Back to the Future trilogy. The
film stars Michael J. Fox, Christopher Lloyd, Thomas F. Wilson, and Lea
Thompson and continues immediately following the original film. After
repairing the damage to history done by his previous time travel
adventures, Marty McFly (Fox) and his friend Dr. Emmett "Doc" Brown
(Lloyd) travel to 2015 to prevent McFly's future son from ending up
imprisoned. However, their presence allows Biff Tannen (Wilson) to steal
Doc's DeLorean time machine and travel to 1955, where he alters history
by making his younger self wealthy.
The film was produced on a $40-million budget and was filmed
back-to-back with its sequel, Part III. Filming began in February 1989
after two years were spent building the sets and writing the scripts.
Two actors from the first film, Crispin Glover and Claudia Wells, did
not return for the final two. While Elisabeth Shue was recast in the
role of Wells' character, Jennifer, Glover's character, George McFly,
was not only minimized in the plot, but also was obscured and recreated
with another actor. Glover successfully sued both Zemeckis and Gale,
changing how producers can deal with the departure and replacement of
actors in a role. Back to the Future Part II was also a ground-breaking
project for effects studio Industrial Light & Magic (ILM): In
addition to digital compositing, ILM used the VistaGlide motion control
camera system, which allowed an actor to portray multiple characters
simultaneously on-screen without sacrificing camera movement.
Back to the Future Part II was released by Universal Pictures on
November 22, 1989. The film receiving mixed to positive reviews from
critics and grossed over $331 million worldwide, making it the
third-highest-grossing film of 1989.
Plot
On October 26, 1985, Dr.
Emmett Brown arrives in his flying time machine and persuades Marty
McFly and his girlfriend, Jennifer Parker, to come back to the future
with him to help their future children. Biff Tannen witnesses their
departure. They arrive on October 21, 2015, where Doc electronically
knocks out Jennifer and leaves her asleep in an alley, explaining that
she should not have too much knowledge of future events. He has Marty
pose as his own son and lookalike Marty Jr to refuse an offer to
participate in a robbery with Biff's grandson Griff, thus saving both of
Marty's children from prison.
Marty switches places with Marty, Jr., and refuses Griff's offer, but
Griff goads Marty into a fight. Griff and his gang are arrested, saving
Marty's future children. Before rejoining Doc, Marty purchases an
almanac containing the results of major sporting events from 1950 to
2000. Doc discovers it and warns Marty about attempting to profit from
time travel, but before Doc can adequately dispose of it, they are
interrupted by the police, who have found Jennifer incapacitated and are
taking her to her 2015 home. They pursue, as does Biff, who has
overheard their conversation and picked up the almanac which Doc
discarded.
Jennifer wakes up in her 2015 home and hides from the McFly family. She
overhears that her future self's life with Marty is not what she
expected, due to his involvement in an automobile accident. She
witnesses Marty being goaded by his co-worker Douglas J. Needles into a
shady business deal, which leads to Marty's firing. Attempting to escape
the house, Jennifer encounters her 2015 self and they both faint. While
Marty and Doc attend to her, Biff steals the time machine and uses it
to travel back to 1955 and give the almanac to his younger self to get
rich betting, then returns to 2015. Marty, Doc, and an unconscious
Jennifer return to 1985, unaware of Biff's actions.
The 1985 to which they return has changed drastically: Biff has become
wealthy and corrupt, and has changed Hill Valley into a chaotic
dystopia. Marty's father, George, was killed in 1973, and Biff has
forced Marty's mother, Lorraine, to marry him. Doc has been committed to
an insane asylum. Marty and Doc decode evidence that 2015 Biff took the
time machine to change 1985, and Marty learns from 1985 Biff that he
got the almanac on November 12, 1955. Biff attempts to kill Marty, but
Marty flees and returns to 1955 with Doc.
Marty secretly follows the 1955 Biff and watches him receive the almanac
from his 2015 self. Marty then follows him to the high school's dance,
being careful to avoid interrupting the events from his previous visit.
Marty and the 1955 Biff steal the almanac back and forth, but Marty and
Doc retrieve it and leave Biff to crash into a manure truck. Marty burns
the almanac, reversing Biff's changes to the timeline, as Doc hovers
above in the time machine. Before they can return to 1985, the machine
is struck by lightning and disappears. A Western Union courier
immediately arrives and delivers a letter to Marty; it is from Doc, who
explains that he was transported back to 1885. Marty races back into
town to find the 1955 Doc, who had just helped the original Marty return
to 1985. Shocked by Marty's sudden reappearance, Doc faints.
