Goofs

In the beginning, Sweeney's teeth appear to be in very poor shape; however, by the time he first picks up the tea kettle in his apartment his teeth are considerably whiter and straighter.

Because of the actress's real-life pregnancy and filming out of order, Mrs. Lovett's chest size varies greatly throughout the movie.

When Sweeney Todd knocks Adolfo Pirelli with the teapot, he hits him downward, but Adolfo's head moves upward as if hit from below.

Toby's meat pie changes size a couple of times when he is talking to Mrs. Lovett.

It makes no sense that Toby would find a finger tip in his meat pie, firstly because shots of him looking around the room seem to indicate the hands are separated from the meat that is ground, and secondly because an entire finger tip could of course never fit through the small meat grinder holes even if the hands were ground along with the other meat.

When Turpin meets Anthony, he mentions 'catamites of Greece' in reference to 'everything you've ever dreamed of doing with a woman.' However, catamite is the word for a pubescent boy who has sex with grown men.

Turpin sentences a child to death. However, the youngest person given the capital punishment in 19th-century England was John Any Bird Bell (14) hanged in 1831.

When Toby looks over the bones, rib cages & feet, there is not a single rat, maggot, fly or cockroach to be seen. With no refrigeration, the scraps of meat would rot, quickly bringing pests.

Todd kills Perelli with a kettle that has just come to boil. Not only does no water spill out when Todd swings, he then holds the kettle in both hands. He would have been badly burned.

Lovett's signboard reads 'Mrs. Lovett.' However, the British spelling doesn't use the full stop in Mrs.

When Signor Pirelli is singing during the contest, he makes the sign of the cross, but he does it with his left hand instead of his right, which not usual for a Catholic. There are two explanations for this. One: Pirelli is left handed (see Trivia) and uses this hand indefinitely. Two: Pirelli lies about his entire persona, so he might as well be lying about his religion as well.

The razors are said by Todd to be silver, but if they were genuine silver they would have been badly tarnished after 15 years.

However, given Mrs. Lovett's feelings for Todd, first revealed in the song "My Friends" which immediately follows that line, it isn't out of the question to think that she polished the razors occasionally and kept them in good condition.

In the "by the sea" song fantasy sequence at the beach, Mrs. Lovett is shown wearing sunglasses, which weren't invented for outdoor wear until 1929, and her bathing suit is more of the fashion worn at the end of the 19th century. Sweeney Todd is also wearing a late Victorian suit. The movie is set in 1846. One must remember, though, that this is Mrs. Lovett's fantasy. For all we know, she could've been the first person to conceive these fashions.

Although the actual mechanism of the chair is not shown, the pedal which Sweeney pushes to open the trap door and send the chair back appears to be switching sides of the chair throughout. There could be two pedals, one on each side, that operate the same mechanism.

Sweeney Todd wields a boiling teapot with two hands around the heated pot to hit Pirelli on the head. He shows no ill effects of the burn he should have incurred.

When Todd hits Pirelli with the kettle, no water comes out of it. However, when Todd drops the kettle, the water spills onto the floor.

Based on the layout of Mrs. Lovett's Bakery and Sweeney's shop upstairs, there is no physical way the chute for the bodies could go directly to the basement. The bodies would have to pass through Mrs. Lovett's bakery.

The barber chair is at the picture window, which means the chute would be depositing the bodies in front of the table where Sweeney first ate his meat pie.

When Anthony goes into the blonde room to rescue Johanna there is clearly a man with dark hair sitting near the entrance.

If you look closely you can see that the baby that Johanna's mother is holding is really a doll.

At the start of the film, as Todd's ship arrives, a completed Tower Bridge is seen. Construction of Tower Bridge started in 1886 and it wasn't completed until 1894, at least 50 years after the film is set.

When Pirelli pulls out an Italian flag, it is the current type - tricolor. Not the pre-1946 flag which had a coat of arms on the white bar.

When baby Johanna is lifted in her first scene, she clearly is wearing modern, plastic diapers.

Todd looks at photos of his wife with their baby daughter, but photography (in its daguerreotype form) was invented only around 1839.

In the beach scene, Todd and Lovett are wearing light, striped swimwear entirely based on early 20th-century designs.

When Toby beats the drum to attract people's attention on the street, the sounds are very clearly out of sync with him actually beating drum.

At the end of "A Little Priest", when the camera zooms out, Sweeney Todd and Mrs. Lovett's mouths suddenly close and you can only hear Todd singing.

The white stripe in Sweeney's head changes sides. Just before Judge Turpin arrives for a shave, the stripe is on the left side and stays there throughout the "Pretty Women" song.
