Released this very weekend in 1985 and kickstarting the movie career of Michael J. Fox, 'Back To The Future' went on to spawn two sequels and forever associated the Delorean DMC with time travelling.
A critical and commercial success on its release, 'Back To The Future' has since become one of the most popular sci-fi comedies of all time, not to mention being the touchstone for any and all time-travelling comedies since its release.
