It's been said that, because of his relatively short stature, Milburn Stone's (Capt. Vickery) lower extremities are rarely shown in this movie and that he had to stand on a box in order to be taller than his love interest, Sally Musgrave (Hillary Brooke). Stone, best known as Doc Adams in the long running western Gunsmoke, was only 5'8". However, this appears to be an apocryphal assessment regarding their relative heights since Hillary Brooke was 5'6".
Hurry up, lads. Drink up. Five minutes to closing time.
When Holmes is on the floor firing the gun at the wall there are seven holes when he is done firing. Seven shots are heard. The pistol appears to be a six shot .38 caliber revolver. Since he was conducting an experiment, there was no opportunity to reload.
Milburn Stone is said to have been 5' 8" and Hillary Brooke is said to have been 5' 6". There is definitely a discrepancy somewhere or is there? Stone is taller than Brooke.
