The 1989 scifi comedy Back to the Future Part II stars Michael J. Fox, Christopher Lloyd, Lea Thompson, and Thomas F. Wilson. It is produced by Bob Gale and Neil Canton. The director is Robert Zemeckis.The story begins right where its predecessor left off. It is October 26, 1985 when Marty McFly and his girlfriend Jennifer are about to take a ride in his new truck. But Dr. Emmett L. Brown, or “Doc”, abruptly appears in his time-travelling DeLorean and urges the two of them to return to the future with him in order to do something about their kids. Marty’s son is caught in a robbery that Griff Tannen, the bully and grandson of Biff Tannen, had pushed him into. He is sentenced to 15 years in the state penitentiary. Their daughter Marlene is later sent for 20 years for attempting to break him out. These events gradually lead to the destruction of the McFly family. Doc’s plan is to have Marty pose as his own son in order prevent Marty Jr from ever being involved in the robbery. Doc also induces Jennifer to sleep after she asks too many questions about their future. She is left unconscious in the alley while Marty and Doc follow the plan. After the elder McFly says no to Griff about the robbery, the bully challenges him to a fight. When Marty escapes the fight, a hoverboard chase ensues around the courtyard, ultimately resulting in Griff and his gang crashing through the windows of the clocktower and being arrested themselves. Just before meeting back with Doc, Marty purchases a sports almanac in hopes of placing a few bets. Upon discovering this, his friend warns him about trying to financially benefit from time travel and throws away the almanac. Old Biff, having overheard Doc’s lecture, decides to steal the time machine and give the book to himself sometime in the past in order to make himself rich and powerful. Meanwhile, Doc and Marty must follow some police officers who had found Jennifer conscious in the alley and taken her to her future home. After seeing her future self and passing out again, Marty and Doc retrieve Jennifer from the house. During this time, old Biff had stolen the time machine and gone back to give the sports almanac to himself at some point in the past. Marty, Jennifer, Doc, and Einstein (Doc’s dog) return to 1985 thinking it was the same as it was when they left. But, instead, Marty finds different people living in his house and, later, discovers that Biff controls the entire town of Hill Valley and is married to Marty’s mother. He also sees that his father, George McFly, was murdered 12 years earlier by Biff. Biff is abusive to his wife and her children, all the power having gone to his head. Doc and Marty decide that the only way to restore the old 1985 is to go to November 12, 1955, the date old Biff gave young Biff the almanac.One concept of the movie that I find interesting is the new inventions found in the future. In the year 2015, the technology is far more advanced. All cars can be hover-converted to fly. The DeLorean itself has been hover-converted and can now fly. Additionally, one doesn’t need a key to enter his home. He can simply press his thumb to a plate beside the door and it will open for him with a greeting like, “Welcome home, Marty!” Next is the advanced 3-dimensional images that Marty encounters early in the film. There is an image of Jaws popping out of water and opening its mouth to swallow him up. Marty screams only to have the image disappear. Then he says, “Shark still looked fake.”Another fascinating feature of this movie is the hoverboard chase scene early in the film. It parallels the chase scene in its predecessor. In Back to the Future, the chase scene takes place with Marty trying to avoid Biff and his gang. In Back to the Future Part II, the pursuit of Marty happens in the same area only with Biff’s grandson Griff and his gang. But perhaps even more surprising is that in Part II, the familiarity between the two scenes is actually acknowledged when Biff says, “There’s something very familiar about all this.” Yet, there are some differences. The scene in the first movie ends when Biff crashes his car into a manure truck whereas in the second movie, it’s over when Griff accidentally crashes his Pit Bull board into the courthouse’s front windows and gets arrested.To wrap, if you like a good time-travelling story, this is your kind of movie!
