Filming of the locations started on October 9, 1972 at the harbor in Plockton. Preliminary footage which was originally shot to make up a showreel to sell the film to studios were shot in that summer. These scenes included the aerials of the orchards (shot in South Africa), and the phallic topiary and the pregnant women touching the apple blossoms which were shot at actor David Hemming's house at Hush House Manor in Kent, England.
The crew used a converted double decker bus as a film editing and screening room. Location Studios was written on its side. You can see pictures of it here:
The crew of almost 70 was based in Newtown-Stewart so film was sent to Humphries Laboratories in London where it was processed, tnen sent back to Newton-Stewart.
Auditions for extras were on Douglas House on King St in Newton Stewart.
