The Chevrolet commercial at Castle Rock

(February 19, 2015) One of the most famous — and memorable — automotive television commercials of the 20th Century was made by Chevrolet, advertising the 1964 Chevrolet Impala convertible.

General Motors airlifted the convertible along with a model onto a slender 400-foot-high pinnacle at Castle Rock east of Moab, Utah. In the commercial, filmed from high above the rock, music swells and a deep voice intones, "In a class of its own, it stands alone." The Impala appears perched on the edge of the rock as the actress sits on top of the seat and waves.

According to one account, the model was stranded on the rock with some of the search and rescue crew for several hours after the shoot because of high winds that made it impossible for the helicopter to land.

The commercial was filmed by Alexander Film Company from Colorado Springs.
