Cliff Culley, of Westbury Design, handed the task of creating the cave to the highly experience Roy Field whom he had worked with for some time and was a specialist in models and their filming.
To achieve the effect, Field used Commercially available ‘Louis Marx’ Dalek toy. But to save money only a few were bought and most of the Daleks were made by using the toy as a mould from which many were made from plaster.
Some of the actual toys were used and moved in the model sets but most were static alongside the models.
To Create the mould the gun mount was removed from the toy. A wooden replacement was attached to the models and a golf tee was used to create the eye stalk. The models were painted to match the main Dalek props.
