The absurd nuclear-powered Cyclops in The Big Bus was not merely a miniature or a studio mock-up. For James Frawley’s 1976 disaster satire, production designer Joel Schiller oversaw the construction of a large, road-worthy double-decker articulated bus with 32 wheels. The visible front section contained functioning cockpit and lounge areas, while much of the remaining body was largely hollow, carrying only the engine, suspension, and mechanisms necessary for driving and exterior stunt shots. The vehicle was so substantial that it appeared in Los Angeles’s 1976 Bicentennial Parade and was later driven from Los Angeles to San Diego as part of the film’s promotion, with Trailways Bus Lines assisting the production.
The strangest engineering complication was that Cyclops’s rear half was a separate vehicle. The two sections were transported independently, joined for filming, and operated by different drivers. According to contemporary trade coverage, the driver in the rear section had no forward visibility and had to maneuver solely through radio instructions from the crew. That arrangement produced one of the film’s most convincing mechanical gags: as the bus makes a sharply restricted turn leaving the terminal, the front wheels of the rear section visibly steer independently. The enormous prop apparently survived only briefly after its cinematic career; later accounts state that it was eventually scrapped, leaving the bizarre 32-wheeled stunt machine as a largely vanished relic of 1970s movie engineering.
