- Moral Event Horizon: For most of the short, Hugh is a bully who scares other into working for him, but he undoubtably goes too far when he starts assaulting Daphne and nearly kills Tiny.
- Nightmare Fuel: Mr. Hugh soul being taken away by the ghostly organist, who rises out of the orchestra pit and, presumably, takes him to hell.
- Visual Effects of Awesome: In addition to the excellent character animation, especially on the dogs, which were mere inches high, making them notoriously difficult to animate, there's also the double-exposed Mr. Hugh being taken away by the glowing, ghostly organist.
- The Woobie: Tiny. To a lesser extent, Daphne.
The Hitchcock Film:
- Alternate Character Interpretation: The Reveal throws Charlotte's character into a different light. Jonathan murdered her husband for her. He claimed she made him do it but how true is that? Although she doesn't seem sad about her husband's death, she's perfectly nice to her employees, and is it possible Jonathan just did this on his own and Charlotte got caught in the crossfire? Or is Charlotte even more manipulative than she appears? Did she attract Jonathan knowing his history, hoping he would commit the murder for her? She notably drops him pretty quickly once she thinks she's in the clear.
- Hilarious in Hindsight: In a couple of years, there would be another thriller about a manipulative actress with a character called Eve.
- One-Scene Wonder: Joyce Grenfell as the pompous lady operating a shooting game at the garden party. Kitty Hollywood in her review notes that she almost "walks away with the film". In the credits she's only listed as 'Lovely Ducks'.
- Romantic Plot Tumour: Subverted brilliantly. Eve's growing romance with Smith seems to take time away from the main plot, but it pays off when Eve's love for Smith is what convinces her to refuse to help Jonathan when she discovers he's a murderer.
- "Seinfeld" Is Unfunny: The twist here is that Jonathan was lying the entire time. Audiences were shocked at the time, and felt they had been cheated. The reaction was so negative that Hitchcock himself apologised for it. With the Unreliable Narrator trope becoming quite common these days, modern viewers would be de-sensitised to such a thing. Viewers might also pick up on how evasive Charlotte's dialogue with Jonathan is.
- Values Dissonance: The baffled looks that the punters give Eve when she walks into the bar might seem odd to a modern viewer, likewise Eve's hesitation before going in. In those days a young woman wouldn't dream of going into a pub alone. This is underlined by her mother's annoyance that that's where she met Smith.
