Corrected entry: During the market scene before we see Pereli, Mrs. Lovett says the Italian (Pereli) is here every Thursday. But in the next scene, Sweeney asks why Beetle isn't here yet, and she says, "He will be there when the week is out; it is only Tuesday."
Corrected entry: In the scene where Todd attacks Pirelli with the teakettle, he first swings it from the right to left, then you see Todd for a split second swing it in a downward motion, but Pirelli's head moves up as if Todd just swung it in an uppercut motion.
Correction: If you watch, you can see Pirellis's head snap downward and then snap back up- a realistic reaction from a downward blow.
Correction: Clearly Sweeney would not be so agitated by the Beadle (they've spelled it wrong as well) not showing yet if this scene were meant to take place directly following the scene with Pirelli. The second scene is meant to take place several days later - on Tuesday. (The quote is, furthermore, "Who says the week's out? It's only Tuesday.") This further clarifies why Sweeney would think the Beadle should have been there by now, as he may have taken "before the week is out" to mean "before Sunday of this week" rather than "by Thursday of next week."
