Back to the Future
Director: Robert Zemeckis
Cast: Michael J. Fox, Christopher Lloyd, Lea Thompson, Grispin Glover
Marty McFly is a teenager who accidentally ends up using a time machine built by his eccentric friend Doc Emmett Brown. He ends up in 1955, where he has to play a matchmaker to his own parents to make sure he will be born. This supremely entertaining time travel adventure has become a genuine classic for a reason. It offers great performances, lovely characterisation, and an incredibly inventive script. Followed by two sequels, Part II and Part III.
