Back to the Future is a 1985 American science fiction film directed by Robert Zemeckis, and starring Michael J. Fox, Christopher Lloyd, Lea Thompson, Crispin Glover, and Thomas F. Wilson. Set in 1985, the story follows Marty McFly (Fox), accidentally sent back to 1955 in a time-traveling DeLorean automobile. While there, Marty prevents his parents from falling in love, threatening his existence unless he reconciles the pair. Eric Stoltz was initially cast as Marty, but after filming began, Zemeckis determined he was not right for the part and hired Fox, re-filming scenes already shot. The film was the highest-grossing film of 1985 worldwide, earning $381.1 million. Critics praised the story, humorous elements, and the cast. It won an Academy Award, three Saturn Awards, and a Hugo Award. Its theme song, "The Power of Love" by Huey Lewis and the News, was also a success. Two sequels, video games, theme park rides, an animated television series, and a stage musical testify to its enduring popularity. (Full article...)
