Alec Guinness performed the stunt of climbing down the side of the mansion. He was convinced by a technician that the piano wire holding him up would not break, since only piano wire with kinks in it would be prone to breaking. As he got to about four feet from the ground, the wire did in fact break.
The sounds of Stratton's experiment were later set to music and released as "The White Suit Samba".
The strange noises made by the laboratory apparatus were produced for the sound track by a tuba and a bassoon.
