Julie centered on Louis Jourdan as a concert pianist who plans to murder his wife, played by Doris Day, who eventually has to assume control of the airplane on which they are flying.

​

Both outdoor and indoor (simulator) shots were taken on Transocean's premise. TAL captains Bill Keating and Royal Minson instructed Doris Day how to handle the simulator controls properly. The camera was positioned behind the simulator, and its windshield was re-moved so that the filming would pick up a "process" screen in front of the simulator. This "process" screen would show all of the aerial views of snowcapped mountains and valleys so it appeared that she was actually flying an airplane.  

    

For filming the landing scene, a large Mitchell camera was mounted in the co-pilot's seat of one of TAL's DC-4s to record the approach through the windshield of the aircraft. To achieve as much reality as possible, the director wanted the landing to appear rough-as though a novice was at the controls. But the pro at the controls was Captain Keating. "I kept the airspeed rather high because we would intentionally bounce the aircraft at least five or six times down the runway for interior and ground cameras.  As a result of the long, fast approach and those bounces-which were between thirty and forty feet high into the air-when we turned off at the end of the runway, the outboard right tire blew out. We couldn't have done better if we'd tried!"
