When Dr. Emmett Brown gets trapped in a Western world in 1885, it's up to Marty to rescue him when he learns of his untimely death. It isn't long before he runs into Biff's ancestor Buford, however, who doesn't exactly make it easy for the pair to get home. Plus, the DeLorean is out of gas which means they can't accelerate to the required speed anyway to travel forward in time. They have an idea, though, involving the use of a rail spur and a train to push them to the right speed, but before they can implement the plan Buford attempts to force Marty into a duel. And after Doc has fallen in love with a beautiful 19th century lady named Clara and been subsequently dumped after revealing his true origin, he's not in the best of moods to help them finally get home either.

The trilogy was completed with 'Back To The Future Part III' in 1990 with Robert Zemeckis ('Forrest Gump', 'Cast Away', 'The Polar Express') once again at the helm. These clips are being released to promote the release of the 'Back To The Future' trilogy box set, which is out now on DVD and Blu-Ray.
