According to the invitation shown on screen, the hunt ball is on March 7, but the telegram that persuades Lina to attend the ball is dated March 8.

Lina pulls a letter from an envelope which is shorter than the book that contains it. But, in the next shot it is evident that the paper she now holds is wider than the length of the book below. The close up of the handwritten note indicates it was written on a much narrower page size.

When Lina is having lunch with her parents, she is sitting on the long side of the table between them. When she returns from the phone, her seat is moved to be right beside her father's.

While playing "Anagrams" and Lina changes the letters MUDDER to MURDER, she slides the D above the word and slides the R in its place. The D is the only upturned tile directly above the word MURDER. After the camera switches to a close-up of Lina and back, the tiles there are now an H and F upturned and two face-down tiles next to them that weren't there seconds ago.

When Lina looks at Isobel's book while Johnnie is on the telephone, there is a large tear in the book jacket above Isobel's photo. In the next scene, when Lina takes the book on her visit to Isobel, the book jacket is undamaged.

The invitation to the Hunt Ball (about 15 minutes into the film) gives the date as Thursday, March 7. In the next scene showing the telegram from Johnnie, the year is shown as 1938. March 7 was not on a Thursday in 1938.

Alfred Hitchcock makes his cameo appearance about forty-six minutes in, posting a letter in the village. However, when the shot changes, he has suddenly disappeared from beside the pillar-box. This is how a cameo works: an appearance, then gone.

In the final scene as Johnnie and Lina drive back home, it is clear from the shot of them from behind that doubles have been used. The two characters in the scene are not Joan Fontaine or Joan Fontaine.

Alfred Hitchcock makes his cameo appearance about forty-six minutes in, posting a letter in the village. Note the background in this shot and a shot just a few seconds earlier with the car driving by and a man walking while smoking. They are both exactly the same background shot with the same car and people, with one being enlarged. It could be the film was so expensive, the re-use of background shots was needed.

The barrister's lips and speech are out of sync when reading Lina's father's will.

The "British" light switches in the sets are unmistakably American. They even operate in the American way - up for on, down for off - the opposite of real British switches.

Although Johnnie admits to Lina, after taking an extremely expensive house, that he is broke, they continue to live there, employ servants, and run a very expensive car. No explanation is made of how they can afford this. The job Johnnie later gets, in an estate manager's office, would pay only a small part of these running costs.

As the game of Anagrams is played, the first tile used to spell MURDER is not an M but a W. Typographically the two are different.
