To make the possessed car scenes work, the stunt drivers used various practical ways of disguising themselves so they would not been seen behind the wheel of the car. In some scenes they crouched down below the dash. In the scenes where the car was filled with dark shadows the driver dressed all in black from head to waist to blend in the shadows.

The car is a 1939 Lagonda V12 Rapide Drophead coupé.
