 Evans remembered that the location filming involving Gabriel, conducted in and around Burnham Beeches in Buckinghamshire in the autumn of 1968, proved to be arduous due to the low levels of light. On occasion, just two minutes of new footage would be recorded at each session. On the subject of the remote-control steering, he stated, "I remember standing out of shot and having to 'drive' [Gabriel] 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 location unit member would be on hand to stop the car with a large cushion if it went out of control.
