Continuity: When Gay gives Mr. Keane a drink, she completely empties the cocktail shaker. However, after she gives him the drink, she takes the same cocktail shaker and supplies a drink for herself.
Continuity: When Latour is seen in close-up in the court, there is a man on either side of him. In the long shots, there is nobody near him.
Factual errors: Although the film story is all based in UK, but almost all of the characters speak in an American accent.
Continuity: When Keane goes to the Paradine house in Cumberland, he walks over to Mrs. Paradine's piano. On the piano we see close-up of a page of music called Appassionata Op. 69 by Francesco Ceruomo. But in the next scene, when we see Keane passing by the piano, none of the three pages on it have any title at the top, only music, showing they are subsequent pages of that piece, and not the first one, as shown in the close-up.
Audio/visual unsynchronized: Latour is in shadow when he first meets Mr. Keane, but it is plain that his lips are not moving when he speaks.
