The adventures of Marty McFly (Michael J Fox) conclude in a Western setting, when Marty discovers the name of his time-travelling pal, Doc Brown (Christopher Lloyd), on a tombstone saying he was shot back in 1885. So, adopting the name Clint Eastwood, McFly jets back to 1885 to stop it happening, but Doc's reluctant to return to 1955, as he's fallen for teacher Mary Steenburgen. The film-makers definitely saved the best for last with this terrific final part of the trilogy, with great special effects and plenty of laughs.
