The Mount Rushmore National Memorial is a sculpture carved into the granite face of Mount Rushmore near Keystone, South Dakota. Sculpted by Danish-American Gutzon Borglum and his son, Lincoln Borglum, Mount Rushmore features 60-foot sculptures of the heads of four U.S. presidents: George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln.

Mount Rushmore appears in the final scene sequence of North by Northwest. But, apart from initial shots and footage in the car park, both the cafeteria and the climatic chase across the historic monument were filmed at the MGM studio and sound stage locations.

When the film was in pre-production, the National Park Service had granted tentative permission for location filming on the strict proviso that no scenes of violence would be filmed "near the sculpture on the talus slopes below the structure" or on "any simulation or mock-up of the sculpture or talus slope." The permit was subsequently withdrawn by the Department of the Interior after a newspaper published an interview with the director, Alfred Hitchcock, where he described how he was planning a violent chase across the granite faces of the presidents.

With this movie, the hope is that Mount Rushmore serves as the essence of America. The country endures; the good guys win. The spies whoever they are obviously lose; the mountain is the clear winner. The mountain's spirit which is America totally prevails.
