Factual error: When Sweeney is sharpening his blades, most noticeably during the shaving contest, he is sharpening toward the blade, which you simply can't do with a razor blade and leather strop. A razor will slice right into the leather. He also doesn't even have the blade flat to the leather so again they're not remotely sharp as a sharp blade would easily sink right into the leather. Pirelli is using roughly the correct technique, even though they're trying to portray him as sloppy. (00:35:50)
Sweeney Todd (2007)
1 factual error - chronological order
Directed by: Tim Burton
Starring: Johnny Depp, Helena Bonham Carter, Alan Rickman, Timothy Spall, Sacha Baron Cohen
Other mistake: At the end of the song "Wait," when Sweeney and Lovett hear Anthony running up the stairs, Sweeney runs behind the door to his shop. For a quarter second, as Sweeney places his back against the wall, there is a modern-day water bottle on the window ledge. This, however, cannot be seen on the DVD or Xbox, though on laptops and probably computers also, when streaming you can see it around 00:43:10. (00:43:10)
Sweeney Todd: No! Not Barker. That man is dead. It's Todd, now. Sweeney Todd. And he will have his revenge.
Trivia: Anthony Stewart Head (of "Buffy the Vampire Slayer" fame) makes a cameo as the man who congratulates Sweeney after his competition against Signor Pirelli. Head originally had a larger role, but his scenes were eventually cut out. (00:38:25)
Question: In Mrs. Lovett's song "By the Sea," near the end she sings "Bring along your chopper!" What is the word "chopper" supposed to mean? Sweeney can bring his what?
Answer: His knife/razor/sharp edge to kill someone with.
