"Would I have become friends with my father if I went to school with him?"
That question was the germ (courtesy of producer/co-writer Bob Gale) for a film that eventually became science fiction classic Back to the Future (1985). Gale and director/co-writer Robert Zemeckis teamed up with the legendary Steven Spielberg to finance and create the film, which chronicles Michael J. Fox's Marty McFly as he travels back in time with the help of the eccentric Doc Brown's Plutonium-powered time-traveling DeLorean. However, once Marty arrives in the past, he finds out that he doesn't have enough Plutonium to return. Since Plutonium is nigh-impossible to obtain, he enlists the help of a younger Doc Brown to figure out how to return home with causing irreparable damage to the timeline.
Back to the Future was a fantastic critical and financial success after it was released. On movie review site Rotten Tomatoes, it has a critics rating of 96% and an audience rating of 94%. On movie site IMDb, the movie has a rating of 8.5 out of 10 stars. After he gave the film a rating 3.5 out of 4 stars, renowned film critic Roger Ebert wrote of the film: "This time, the match [with Zemeckis and Spielberg] works with charm, brains and a lot of laughter." The movie was also nominated for four Academy Awards (one of which it won): Best Sound Effects Editing (the only one it won), Best Original Screenplay, Best Sound, and Best Original Song for "The Power of Love" by Huey Lewis and the News. It received the great honor of being selected for preservation into the National Film Registry.
This film spawned a very successful franchise. It had two sequels, aptly titled Back to the Future Part II and Back to the Future Part III. Both of which were critically and financially successful, but not as successful as this film. Besides sequels, the movie spawned an animated T.V. series, a theme park ride, and a number of video games.
