Zemeckis wrote the story, along with Bob Gale. It stars Michael J. Fox as teenager Marty McFly and Christopher Lloyd as mad scientist Doctor Emmett L. Brown. The story's basic plot concerns Marty's accidental traveling back to the year 1955 in a time machine that Doctor Emmet Brown constructed. This causes a number of problems, such as how he will be able to return to 1985, where he came from, when he does not have the necessary plutonium to fuel the journey. He also inadvertently interferes with his parents' first meeting in 1955, and must get them to fall in love before he goes back to 1985. The film opened on July 3, 1985, and grossed U.S. $210 million at the U.S. box office, making it the highest grossing film of 1985.[1] The film was followed by two sequels, Back to the Future Part II in 1989 and Back to the Future Part III in 1990, forming a trilogy. On December 17, 2002, Universal Studios Home Entertainment released the film on DVD and VHS as part of Back to the Future: The Complete Trilogy. Due to the film's success, three spin-off projects were made. CBS TV aired an animated series, Back to the Future: The Animated Series and Harvey Comics released a handful of similarly styled comic books, although their stories were original and not merely duplicates of the films. In 1991, Universal Studios Theme Parks opened a simulator ride based on the series called Back to the Future: The Ride. The ride closed on March 30, 2007 in Orlando, FL, and September 3, 2007 in Hollywood, California. The ride remains open at Universal Studios Japan.

On the morning of October 25, 1985, his eccentric friend, scientist Dr. Emmett "Doc" Brown (Lloyd), calls him, asking to meet at 1:15 a.m. After school that day, a solicitor approaches Marty and his girlfriend Jennifer (Claudia Wells), asking for donations to preserve the town's clock tower which has not run since it was struck by lightning thirty years before. Upon arriving home, Marty finds the family car wrecked in the driveway. Inside the home, he finds his neurotic father George (Crispin Glover) being bullied by his supervisor Biff Tannen (Thomas F. Wilson), who wrecked the borrowed car. At dinner that night, Marty's mother Lorraine (Lea Thompson) recounts how she and George first met when her father hit George with his car. "Doc" Brown, (Christopher Lloyd) and Marty McFly, (Michael J. Fox) watch as the time machine vanishes.That night, Marty meets the Doc as planned in the parking lot of Twin Pines Mall. Doc presents a De Lorean DMC-12 which he has modified into a time machine. As Marty videotapes, Doc then explains that the car travels to a programmed date and time upon reaching eighty-eight miles per hour using plutonium in a nuclear reaction to generate the 1.21 gigawatts of power it requires. Demonstrating how to program the machine, Doc enters in November 5, 1955 as the target date, explaining that it was the day he conceived the idea of the flux capacitor; the device which "makes time travel possible." Before Doc can depart for his planned trip twenty-five years into the future, a pair of Libyan terrorists, from whom he stole the plutonium, arrive in a Volkswagen van and ruthlessly gun him down. Marty jumps in the De Lorean and is pursued by the Libyans until he hits eighty-eight miles per hour and is instantaneously transported to 1955. The car stalls shortly after his arrival, so Marty hides it and makes his way into town, finding that the town square now reflects the popular culture of the 1950s. He runs into his own father, then a teenager, being tyrannized just as he was in 1985 by Biff, then the school bully. Marty follows George, and as he is about to be hit by Lorraine's father's car, Marty saves his father by taking the hit himself resulting in Lorraine becoming infatuated with Marty instead of George. Marty is disturbed by her sexual advances which contrast her prudish attitude in 1985. He leaves to track down the Doc of thirty years ago. After managing to convince the scientist that he is from the future, Doc learns of the power requirements of the De Lorean from Marty's videotape. He tells Marty that aside from plutonium, which is unobtainable, the only possible source of that much power is a bolt of lightning, which is unpredictable. Marty realizes that the lighting strike at the clock tower will occur the following Saturday, and Doc concocts a way to harness the bolt's power. However, Doc deduces that Marty has prevented his parents from meeting. Since Marty will not exist unless his parents fall in love, he finds that Marty is in danger of being erased from time. After several failed attempts at playing matchmaker, Marty eventually works out a plan to have George appear to rescue Lorraine from his own advances on the night of a school dance. When Biff shows up unexpectedly and attacks Lorraine, George manages to defend her for real, knocking Biff out with a single punch. Lorraine and George return to the dance together where they kiss for the first time, ensuring Marty's existence. Doc, meanwhile, has used cables to connect the clock tower's antenna to two lamp posts, which he plans to have Marty drive under in the De Lorean, now sporting a lightning rod, at eighty-eight miles per hour the moment the lightning strikes. The clock tower gets struck by lightning at 10:04 P.M. on November 12, 1955Before Marty can leave, Doc finds a letter in his coat pocket that Marty had written, warning him about his future assassination. Doc rips up the letter without reading it, knowing the dangers of learning about the future. Marty adjusts the time machine to take him back to 1985 ten minutes earlier than he left, giving him time to prevent the shooting. Upon his arrival, however, the car stalls and Marty arrives at the mall too late to save the Doc. When the coast is clear, Marty runs to Doc's body and finds him alive. Doc unzips his radiation suit to reveal a bulletproof vest, and shows Marty the letter he had written in 1955, taped back together. The next morning, Marty finds his family has been changed for the better. Most notably, Lorraine is no longer prudish, and George has become self-confident, ordering around Biff, who is no longer his boss, though he seems to be a bit more lenient with him. Just as Jennifer and Marty reunite, Doc arrives from the year 2015, appearing frantic about a problem with the couple's future children. Marty and Jennifer climb aboard the De Lorean and, aided by the technology of thirty years hence, the car lifts off into the sky. [edit] Production [edit] Script The ins
