The future director John Glen was working in the editing department at Shepperton Studios when the film started production. He had a similar build to Joseph Cotten and was enlisted to supply the sound of his footsteps in post-production sound dubbing. He watched a continuous loop in the Westrex theatre and memorized the exact speed of Cotten's pace before dashing outside to a stairwell with a hard surface where the sound of his walking was recorded.
