Factual error: In the scene in Venice where Marge is leaving on the boat with Dickie's father, there is a shot from Tom's point of view looking out onto the water. In the distance a modern crane can be seen on the left - something that the director Mingella himself points out on the DVD commentary. (02:00:00)
Factual error: The opening scene is shot on a rooftop on Central Park West in New York City. The movie takes place in the 40s or 50s, but there are several modern buildings in the background.
