Of the epic movies that the Hal Roach Studio produced during the 1930s, Topper, starring Cary Grant and Constance Bennett, still remains a classic to this day. The comedy follows a plot that is zany at best, as the two stars play husband and wife, and are killed in a car crash. In order to ascend to the great beyond, they are required to perform a good deed on earth and decide to show their snooty banker, Cosmo Topper, the lighter side of life. If it weren’t for the car the studio had designed for the movie, the film would still be a favorite for late night movie buffs, but certainly would not have become a cult favorite for old car enthusiasts and gas and oil collectors. The Topper car (designed by popular Pasadena, California, custom coachbuilder Bohman and Schwartz) was based on a 193 Buick Roadmaster chassis and went through several transformations in its subsequent use as a promotional vehicle for the Gilmore Oil Company and as the Mobil Special. In the film, Cary and Constance meet their demise when they have an altercation with a roadside tree. Since this is before the days of high-tech graphic design, the studio simulated the effects of the wreck by painting on the dents and scratches. The plot then called for the two stars to become invisible as they went about the task of performing their good deed. The vehicle then took on a prominent role in the film by transporting its invisible passengers, disrupting traffic, and at one point even changing its own tire.
