Goofs

Midday turns to night during Tracy and George's poolside conversation.

When Mike is outside the library, there are no columns visible, but when he enters, the shot from inside the library shows one.

When Mike has drunkenly woken Dexter up and barged into his home in the middle of the night, the top of Dexter's pajama shirt keeps changing from buttoned to unbuttoned.

When Tracy and George talk at the party the night before the wedding, George informs her that "it's after four" in the morning. After that, several hours of activity take place, but it's still dark outside when they all eventually go to bed. Assuming that all this takes place in the summer months, Mike's visit to Dexter's house, Liz's arrival at Dexter's and the typing up of the letter, Tracy and Mike's dancing and swim, and George's arrival on the scene and argument with Tracy and Mike should all have taken place in the bright light of morning.

When Tracy meets Uncle Willie at the stables, she is wearing a jacket in a widely woven plaid, but when she takes the perfume from the drawer in the car, her sleeve is a tweed with no pattern whatsoever. Then, when Uncle Willie pinches her, her jacket changes once again, this time to a box plaid. At the same time, Uncle Willie starts out with a small-patterned wool jacket, but as he reaches to pinch Tracy, it has turned into a hounds-tooth jacket.

In the opening scene Tracy asks her mother how to spell omelette, and she spells it "ommelet'.

The Ardrossan Estate does not have an outdoor pool.

After Dexter reveals Kidd's blackmailing scheme to Tracy, he accidentally calls her Dinah. Correction: Dexter is not calling her Dinah. When he says "Quiet, Dinah" his implied meaning is "Quiet, Dinah will hear you."

When C.K. Dexter Haven is whistling after coming to the mansion, Mrs. Lord calls Tracy "Kathy" instead of Tracy. Correction: the person who wrote this comment must have heard the line, "No, can't be" (American accent) and misheard it as "No, Kathy".

Elizabeth puts her camera an Argus C3 35 MM on the table and the table is accidentally knocked over. The back of the camera supposedly pops open exposing the film, but the camera back is clearly open while on the table.

When George pays his first call upon the Lord home, he bounds down the "stone" steps, landing very heavily on the bottom one, which makes a hollow wooden noise.

When the photographer snaps a photo of the wedding party; everyone stops and stares at him. This frozen moment is what's shown in the following photograph. But the orientation of the people in the real-life moment is different than that of the photograph shown. This includes the facial expressions, the angle of the bodies, the positioning of the people, and the placement of the minister's hands on the bible.

When Tracy and Dexter are talking about the information that Kidd has on her father, Dexter hands her pictures and tells the story of her father and the dancer, Tina Mara. After Tracy shuffles through the paper multiple times, there doesn't seem to be any written or typed text or photographs on this paper.

The shutter sound on Elizabeth's camera doesn't sound anything like a real camera shutter.

In the first scene featuring Mike (James Stewart) and Liz (Ruth Hussey), they are having a discussion in which Liz keeps repeating, "Just that." But right before they go into Sidney Kidd's office, you can see her mouth saying, "Just that," yet there's no sound.

As Connor and Tracy exit the library, the boom mic is reflected on the windshield of Tracy's car.

As Mrs. Lord leaves for the party she calls Mike "Mr. O'Connor" instead of "Mr. Connor".

Mike incorrectly sings "Someday" Over the Rainbow. He sang incorrectly because he was drunk.
