The stepmother starts the music lesson by instructing her daughter to sing in "the pear-shaped tone." The phrase alludes to the pattern resonant sound makes on an oscilloscope — a device developed after the era in which the story is set.
(at approximately 1 hour 8 minutes) As Anastasia kicks the footman into the piano, his head strikes the keys at the extreme left of the instrument, yet higher-pitched notes are still audible — tones that could not possibly originate from that far-left section of the keyboard.
(at around 53 minutes) While Cinderella and the Prince are dancing, just before they step out into the garden, they throw large shadows onto the wall. Those shadows do not mirror their movements.
(at about 1h 3 mins) Moments before the stepmother locks Cinderella in her bedroom, she asks Gus and Jaq what they are warning her about. As the stepmother takes her key, Cinderella turns round while she utters "Oh, no!", yet her lips aren't moving.
Anastasia shouts, "And look — that's my sash! She can't be wearing my sash!" as she tears the sash from Cinderella's dress, but her mouth does not move while she pulls it off.
Whenever Cinderella's bare feet are visible in the film, no toes are shown, the lone exception being the final scene when the Duke places the glass slipper on her foot. The only other human characters whose bare feet are displayed, the stepsisters, are both shown with large, prominent toes.
The slipper that remained on Cinderella's foot once the Fairy Godmother's spell had worn off was the right one; however, when the other slipper had been broken and she hands this slipper to the Grand Duke, he fits it onto her left foot.
(at around 53 mins) While singing "So This Is Love," Cinderella dips her hand in a fountain on the palace grounds despite wearing full-length evening gloves. In reality, no-one would put their hand in water while wearing gloves.
(at around 14 mins) When the mice twist their tails together and Jaq selects one to decide who should distract Lucifer, he doesn't appear to realise he is holding his own tail until the other mice have leapt away, at which point he ought to have already felt his own digits on it.
(at about 59 minutes) When the King flies into a rage over Cinderella vanishing after the ball, he accuses the Duke of being party to "a plot" with the Prince. The nature of this "plot" is never explained.
Anastasia and Drizella are furious that Cinderella is allegedly 'stealing' their beads and sash for her outfit, despite having earlier said they did not want them any more.
When Gus and Jaq are collecting materials for Cinderella's dress and Lucifer spots them, Gus snaps the necklace and Jaq helps him gather the beads. Jaq puts three beads on Gus' tail, the camera cuts to Lucifer, and when the shot returns you again see Jaq placing three beads on Gus' tail.
Cinderella's stepsisters become angry with her for wearing the beads and sash. They regularly treat Cinderella like rubbish and constantly pick on her. Their annoyance at the sash and beads comes from their desire to bully her.
(at around 1 hr 13 mins) During the wedding of Cinderella and the Prince, Cinderella wears a long-sleeved wedding dress. Later, as they wave from the rear window of the carriage, her dress is shown with puffed sleeves.
(around ten minutes in) When Cinderella rouses Lucifer at the start of the film, she opens the door from right to left, yet the shadow of the door on the floor moves from left to right.
(at about 20 minutes in) Gus is tucked beneath the teacup on the tray Cinderella holds in her right hand, which she then hands to Drizella. The tray in her left hand is sent towards Anastasia's room. Yet it is Anastasia who ends up discovering Gus on her tray, when he ought to have been on Drizella's.
At approximately 1 hour 12 minutes into the film, Cinderella's remaining glass slipper is on her right foot, which implies the shoe she lost at the castle belonged to her left foot. When she first sits down to have the lost slipper tried on — prior to it breaking — her right foot is already positioned so the left-foot shoe can be put on.
(at around the seven-minute mark) While Cinderella is getting dressed that morning she fastens a ribbon around the whole of her hair. In the subsequent shot it is tied around only half of her hair.
(at around 6 mins) Cinderella's bedsheet is patched, yet after the birds fold it the patches have disappeared.
(at around 17 minutes in) After Gus drops his breakfast in the kitchen, Lucifer begins to pursue him. As Lucifer sneaks up on Gus, Jaq plucks out one of Lucifer's whiskers. However, when Gus drops his breakfast again and the next shot cuts to Lucifer, the whisker has reappeared.
At about the 22-minute mark, when Cinderella enters the stepmother's room after one of the stepsisters discovers Gus in her breakfast, a shadow is projected behind her. As she draws near to the stepmother's bed, that shadow falls forward across the bed, in front of her.
(at around 5 minutes) Early in the morning, while Cinderella is singing, Jaq is perched on the headboard of the bed; once the palace clock chimes, he is at the foot of the bed.
(at around 45 minutes) In earlier editions of the film, Lucifer's fur appears brown when he attempts to catch Gus, shortly before Gus is transformed into a horse and, startling Lucifer, departs for the ball. This was rectified in subsequent restorations of the film.
(at around 45 mins) When the Fairy Godmother turns the mice into horses, apart from Gus and Jaq she also transforms one mouse with a hat (one of the twins — either Bert or Mert) and another without a hat (the little mouse, Luke). However, when they revert (at around 55 mins), the two mice alongside Gus and Jaq are both Bert and Mert, rather than one of the twins and Luke.
(at around 1h) The morning after the ball, as Cinderella stands by the stairs receiving instructions from her stepmother, the clock beside her shows a different hour from one shot to the next.
(at roughly the 10-minute mark) When Cinderella rouses Lucifer, he emerges from the room, yawns and claws at the floor leaving scratch marks. The next time the floor by the stepmother's room is shown, those scratches have disappeared.
(at about 1h 12 mins) As Cinderella comes down to ask to try on the glass slipper, a tear is visible on her apron; however, after the glass slipper shatters on the floor, that tear appears to have been mended.
Throughout the film, Drizella's ball gown gradually shifts from a yellow-green shade to a paler one.
(at around 38 minutes) In the dressmaking sequence, where the mice are using threads to assemble the dress, a white thread on the left briefly disappears for roughly one second before reappearing.
(at about 52 mins) At the ball the Duke's monocle is damaged during a dispute with the King; he peers at the King through the cracked lens as the King departs. Later, when the Duke goes downstairs to keep an eye on the Prince and Cinderella and pulls the curtain closed on the snooping stepmother, his monocle is whole again.
(at around 36 mins) During the opening scene where the mice are sewing the dress, a pink bow is lifted up to the collar. In the following shot of the dress it's missing, and later the birds use a length of ribbon to fasten the bow.
While the mice and birds are modifying Cinderella's dress for the ball, they add tiers of lace frills to form a collar above puffed pink sleeves. Yet when the dress is revealed to Cinderella, the lace and pink sleeves have vanished and been replaced by white shoulder straps.
(at around 1 hour 2 minutes) The morning after the ball, Cinderella drops the breakfast tray. She gathers the broken crockery and places it back on the tray, but when Anastasia and Drizella hand her their washing, the tray is empty.
(at around 38 minutes) At the end of the dress-making scene Jaq can be seen travelling along a cord from the left-hand side of the screen and entering a chest on two occasions.
(at around 1 hour 10 minutes) When the mice and birds attempt to force Lucifer to drop the teacup so Gus and Jaq can reach the key, the birds fling some crockery at Lucifer in an effort to free Gus. The next time the floor is shown, there is no broken crockery to be seen.
(around the 16-minute mark) Whilst the other mice are scrambling for food, one of them, Jaq, distracts Lucifer by hiding in a hole in the wall, placing his hat on his tail and pushing it out through another hole. Lucifer lunges at the hat protruding from that hole, but when the shot returns to Jaq he is still wearing it.
(at about 1 hr 12 mins) As Cinderella comes down while the Grand Duke is leaving with the slipper, he turns and slips a monocle into place. After speaking to the step‑mother he removes it, yet when he takes Cinderella's hand to help her descend the staircase the monocle is again on his eye, even though he never appears to have put it back on.
(at about 44 mins) Although she normally has to say "Bibbidi-Bobbidi-Boo" each time she casts a spell, the Fairy Godmother somehow lights the pumpkin without having to utter the phrase.
(at around the 55-minute mark) When the horses revert to mice, Gus is at the back with one of the twins. A second later he is at the front alongside Jaq, and the twin who had been with Jaq has moved to the back with his brother.
Throughout the film, the Stepmother's eyes alternate between displaying visible pupils and appearing pupil-less, occasionally switching back and forth within the same scene.
After Gus decides he rather likes his new name and the two look up at Cinderella, Jaq's nose momentarily becomes see-through.
(at around 38 minutes) On the palace clock, as it strikes eight, the eleven o'clock marker displays 'XII'.
(at about 58 minutes) When the Duke tells the King that the Prince wishes to marry the young woman he danced with at the ball (Cinderella), the King cheerfully offers to bestow a knighthood on the Duke. However, as a Grand Duke he holds a peerage; knighthoods can only be conferred upon those who do not hold a peerage (i.e. non-nobles).
Although the Duke is a Grand Duke and formally part of the Royal Family, the King does not treat him as a member of that family.
Light streaming through a door projects Cinderella's shadow onto the far wall beside her. Lady Tremaine's shadow on that wall is shown at the same scale as Cinderella's, despite her being much closer to the light source; in reality, her shadow would be considerably taller and broader.
Cats have retractable claws; however, Lucifer's remain permanently unsheathed, much like a dog's.
On the palace clock face, the Roman numeral for 4 appears as "IIII" rather than "IV". Historically, however, 4 was often rendered as "IIII". The subtractive convention that represents 4 as "IV" is a relatively recent development.
(at around 1h 12 mins) When Cinderella descends the staircase to ask if she may try on the glass slipper, the Stepmother, who had locked Cinderella in her room, does not question how she managed to get out. She is intent on preserving her social composure in front of the Duke. Clearly she will not say anything that would reveal she had locked her stepdaughter in the room.
A previous goof report claimed the full moon shown at midnight during Cinderella's flight in the carriage was improbably close to the horizon except in polar latitudes. In reality the moon does not appear in that carriage scene. Just before the clock begins to strike midnight, when Cinderella and the Prince are on the bridge, the moon is visible as a reflection in the water and could easily be high in the sky. Later, in the pre-dawn view of the palace while the Grand Duke agonises about facing the King, the moon is relatively low but not unreasonably so for a summer night at a hypothetical central European location, which is much further north than most of the United States. This seems a reasonable artistic licence.
(at around 59 mins) As the King loses his temper over Cinderella vanishing after the ball, the Grand Duke initially addresses him as "Your Highness", then, a few moments later, corrects himself to "Your Majesty". However, it is possible that the King’s reaction simply caused the Grand Duke to become flustered.
(at around the 56-minute mark) When the clock strikes midnight, everything reverts to normal except for the glass slippers. This inconsistency is not present in the original fairy tale, where the slippers are simply an ordinary gift from the fairy godmother rather than an enchanted creation.
(at around the 48-minute mark) One of the young women presented to the Prince at the ball is described as a Princess. Why would a Princess, whom we must assume the Prince is already acquainted with, be attending the ball?
A big problem with Disney's version of the story is that, for all the Grand Duke knows, Lady Tremaine organised a *scam* to marry off her most attractive daughter to Prince Charming, thereby making them all members of the Royal Family. Having learnt from the royal proclamation that any maiden whose foot fits a particular glass slipper would become a future queen, Lady Tremaine could have employed a craftsman to spend the night producing a near-replica for Cinderella; she could then have caught the Grand Duke off guard by letting Drizella and Anastasia make fools of themselves, a ruse that conveniently led to the genuine slipper being shattered when, in truth, the stepmother deliberately tripped the footman. With the Grand Duke thus suitably dismayed, Cinderella would then be able to present the fake slipper, which, of course, fits her foot perfectly.
Of all the moments when Cinderella's fairy godmother might have appeared, she does not turn up until the night of the ball.
(at about the 52-minute mark) When the King is dancing down the corridor after leaving the Duke in charge of the ball, light spills from the open door at the far end; even after he shuts the door, the light remains.
When the Grand Duke reads the royal proclamation upon entering the Tremaine household, he recites a version that differs from the notice affixed outside the castle, adding extra lines and rephrasing portions.
