In 1963 Stone directed the filming of a joint project between IBM, NIH, and M. D. Anderson Hospital's Department of Experimental Anesthesiology. The project was developing a monitoring system for a patient undergoing surgery. The main objectives were to keep the anesthesiologist informed of the patient's vital signs and to detect the patient's tendency toward shock. In one scene a computer technician played the role of a patient in surgery while an IBM representative played the role of surgeon, holding a scalpel over the patient's bare midsection. During the filming, the technician asked Stone to tell the cameraman "end of scene" instead of "cut", fearing the IBM rep might get carried away. The comment did get quite a laugh and Stone later passed the story on to Hedda Hopper who added it to her newspaper column. The name of the technician was Loren Block who was attending U of H while working full-time at the hospital.
