A hay rake was put next a rock wall by the killer after he dragged the fox in the bag around the hunting area. In a shot even closer to the end fox hunt the hay rake is pulled away by a tractor for a clearer shot of the field of hunters. After the dog sniffs out the killer, he jumps a horse over the wall and gets killed on the hay rake as he falls from the horse.
The closer shots during the fox-hunting scenes were shot in a studio using rear projection. In these shots, wires can be seen holding the actors and allowing them to move up and down as though riding real horses.
Gwendolynne La Doll's address is shown on the manuscript as being on Fulham Road, London S.W.8., and later dialogue describing the location as "the Fulham Road" makes it clear that this means the main street of that name. But this runs from Fulham to Brompton, whereas the SW8 postal district lies across the Thames in districts such as Battersea and Wandsworth.
