Goofs

As the Rolls leaves the race track, there is no wreath on the front, but there is a wreath on the front as it pulls up to the mansion.

When Shirley MacLaine swims into the Blue Grotto, her hair is wet and stringy, but once inside the grotto, while the rest of her body is still wet, her hair is dry and neatly coiffed.

The car leaves Hotel Imperial in Ljubljana, Yugoslavia with Ingrid Bergman and Omar Sharif to help people because bombs are falling. Moments after it starts moving down street (just left the building), an explosion happens off to the left. Suddenly the car totally vanishes (at around 1h 46 mins on DVD) while the explosion and debris cloud grows. Then there's a change of view/camera angle, and there's a cloud of smoke, and people walk into the street from the right. The car then is seen backing up into view again.

Multiple times during the final (Ingrid Bergman) story the sound effect of the car tires screeching on a dirt/gravel road are heard. This sound happens only on asphalt or concrete, never on a low-traction surface like dirt.

Art Carney and Shirley MacLaine are sitting at an outdoor café after George C. Scott returns to the U.S., and a waiter brings them each a drink in a different type of glass without either one of them seeing or giving their order to anyone first.

In the opening titles, the roofs of modern cars can be seen as the camera pans along Hyde Park.

The movie's last scene shows the Rolls driving north on Manhattan's Henry Hudson Parkway passing under an overhead sign for Interstate 95 in mid-'60s New York City, having been shipped across the Atlantic by freighter some time in between, suggesting the venerable automobile was on to its next new life - perhaps even starring in a film about itself.

Although the first two vignettes of the film are set prior to 1941, Shirley MacLaine's wigs and costumes are all contemporary to 1964.
