Production Company: Amblin Entertainment | Universal Pictures
The finale of the Back to the Future trilogy picks up with Doc Brown (Christopher Lloyd) accidentally being sent back in time to 1885 and Marty is stranded in 1955. Doc is able to leave a message for Marty telling him where the time machine is hidden and Marty gets 1955 Doc help him restore it to working order. Learning that Doc will be shot dead in 1885, Marty decides to go back in time to save him.
In 1885, Marty gets caught up in various Western tropes and discovers that Doc is a successful blacksmith (which he uses as a cover for steampunk-style technology). Lacking fuel for the DeLorean, Marty and Doc work on a plan to have a railroad engine push the car up to 88 miles per hour. Meanwhile, Doc falls in love with the scientifically-minded school teacher, Clara (Mary Steenburgen) and they have to avoid a showdown with Biff’s great-grandfather, an outlaw named Buford (Thomas F. Wilson). Marty also meets his own great-grandparents, Irish immigrant farmers played by Michael J. Fox and Lea Thompson.
Despite being set in the rowdy Old West, Part III feels gentler and less violent than Part II. With only one primary setting the story feels more focused and less gimmicky. This movie still doesn’t hold a candle to the first movie, but it has its charms and humor, and it definitely shows the growth of Marty and Doc’s friendship.
