The third and final installment in the “Back to the Future” trilogy, “Back to the Future Part III” was filmed in Southern California and Monument Valley, Utah. The courthouse square and clock tower appear once again, as the events of the original film overlap with a new timeline. The building can be found on the Universal Studios Lot in Hollywood (100 Universal City Plaza, Universal City, CA 91608). It has been used in countless other films, including “To Kill A Mockingbird,” “Gremlins” and “Bruce Almighty.”  In 2008, a fire destroyed much of the building, but Universal restored and reopened it in 2009.  Today, it can be seen once again as part of the Universal Studios Tour, but this area frequently hosts productions and the site is routinely closed off from the tours.

Doc Brown’s house also appears once again, as Doc struggles to process the idea of another timeline. The house can be found in Pasadena.  Known as the Gamble House, it is a National Historic Landmark and museum, which is open to public tours.  However, only the exterior was used for Doc’s house in the film. The interiors were filmed on a set built on the Universal lot.

LOCATION: 4 Westmoreland Pl, Pasadena, CA 91103

Much of the film takes place in the Old West. The drive in theater scene was filmed in Monument Valley, Utah, while the 1885 scenes were filmed on a set built at the Red Hills Ranch near Sonora, California, with additional scenes filmed in Oak Park and Jamestown, California.

Doc and Marty devise a plan to push the Delorean with a train, in order for it to reach the necessary speed to travel through time. Marty successfully arrives back in 1985 at these train tracks, located in Port Hueneme, California, about 60 miles northwest of Los Angeles. The same intersection and train tracks appear in the film “Ghost Dad.”
