The exterior to Kim Wentworth's home was shot at
Hilfield Castle in
Aldenham,
Hertfordshire. The village scenes and tea shop exterior were shot at The Buttery on Village Road in
Denham,
Buckinghamshire. Laura Slade's cottage was shot on Slade Oak Lane, also in Denham. The episode was actually the third episode to be shot, shot in June–July 1968. The following is an extract from
Dennis Spooner's actual script outline for the scene and aftermath in which Marty discovers somebody other than Randall who can see him: Freddie Jones' stand-in is seen riding a 1963
Triumph Tiger Cub in the opening seconds of the episode. == References ==
