Back to the Future Part III
What's the Story?
Once again picking up right where Back to the Future Part II left off, Marty McFly (Michael J. Fox) gets a telegram from Doc Brown (Christopher Lloyd) explaining that he's stuck in the year 1885, but instructing him not to attempt time travel again. Marty discovers Doc's tombstone, and decides to disregard Doc's orders. Marty dresses up in a cowboy costume and slips into the DeLorean again, landing in the 19th century. He runs into his Irish ancestors (played by Fox himself, and Lea Thompson), and the town outlaw "Mad Dog" Tannen (Thomas F. Wilson), who is Biff's ancestor. Marty finally reunites with Doc, and the two must find a way to refuel the time machine before Mad Dog kills Doc. Complicating matters is the arrival of open-minded schoolteacher Clara Clayton (Mary Steenburgen), who winds up falling for Doc, and forcing Doc to rethink his stance on not changing the past.
Is It Any Good?
Somehow Robert Zemeckis, Fox, and Lloyd make the back-in-time gimmick work, and it's a pleasant surprise. After the mildly disappointing Part II, it would seem that a Wild West-themed threequel would flounder under the weight of too much time-travel confusion and overall Marty and Doc fatigue. The introduction of a love interest for Lloyd may not seem interesting to kid viewers, but as an adult viewing it through grown-up eyes, that subplot with Steenburgen is so much more appreciated. Doc was such a hermit outside of his connection with Marty, that it was a relief to see he could still have a chance at love -- especially with someone as patient and intelligent as Clara. So for the romantics at home, this installment is for you.
Humor-wise, there are plenty of in-jokes for those who've seen the first two films, like Marty's touchiness at being called "yellow." As Marty's rival, Wilson gets to unleash a whole new set of insults as he bullies everyone around him. A heavily accented Thompson returns as Marty's relative, and Fox does double duty again as his own great-great-great grandfather, but the McFly kin has less to do in this one than in the first two; the final film really belongs to Lloyd. One of the funniest moments is the saloon scene where Marty does the moonwalk when he's being shot at; it may take some explaining if your kids don't understand the significance of Michael J. Fox's signature dance move, but it's funny even two decades later. The entire trilogy is still a must-see for parents who want to share a little bit of their own youth with the next generation, even if the children won't laugh quite as hard as you do at some parts.
