The Secret Service [SEP] Filming
The car was fitted with belt-driven electric motors, an upholstered interior, a folding roof and a radio control mechanism so that it could be driven remotely. The location work using the car was conducted in and around Burnham Beeches during the autumn of 1968 and proved challenging as filming was often disrupted by low light levels. On some days only two minutes of footage were recorded. Technician "Wag" Evans, who was responsible for operating the car's radio control, remembered "standing out of shot and having to 'drive' [the car] down the road while it was out of view. Often I didn't know where it was, or where and when it had stopped." A crew member with a large cushion would be on hand to bring the car to a halt whenever it went out of control.
