Twin Pines Mall

The south parking lot where Doc Brown first reached eighty-eight miles per hour.

Puente Hills Mall in City of Industry, California, served as the real-world filming location for the fictional Twin Pines/Lone Pine Mall in the 1985 movie Back to the Future. Starring Michael J. Fox and Christopher Lloyd, this major regional shopping center is most famous for hosting the scenes where Doc Brown stages his time travel experiments with the DeLorean. The mall opened in phases from February 1974 through spring 1975, and its legacy is tied to cinema history. The site features a cross-shaped design developed by The Hahn Company and hosted various anchors over the decades; as of March 2026 two remain.

Lore & Background

Upon returning to October 26, 1985, Marty discovered the sign had changed to Lone Pine Mall, a direct result of his actions in the past. The JCPenney and Robinson's stores feature prominently in the background of these scenes, which were filmed in January 1985 at the mall's south parking lot. Three months after the theatrical release, fans gathered at the actual Puente Hills Mall in the early hours of October 26, 1985, the date given in the film as the present day, to see if anything would happen. In October 2015, the mall honored this legacy by displaying replicas of the Twin Pines Mall sign, the time machine, and Dr. E. Brown Enterprises truck in its parking lot.

Reader's Guide

For visitors seeking the authentic Back to the Future experience, the key is the south parking lot where Doc Brown conducted his experiments. While the mall has undergone significant changes since filming—including a full interior makeover in 2007 after the removal of an East Asian-style koi pond—the location remains a pilgrimage site for fans. As of March 2026, AMC Theaters and Round One Corporation stand as the final two remaining anchors; former anchors include Sears, Forever 21, Macy's and Ross, which closed on January 16, 2026. The mall also incorporated feng shui principles in redesigns to cater to the influential Asian immigrant populations in nearby areas like Industry and Hacienda Heights. Although the JCPenney store featured in the film closed in 1996, the site's connection to the movie remains its most defining characteristic.
