Other mistake: Based on the location of the barber's chair with the picture window in Todd's barber shop and the layout of the exterior of the building, there is no possible way that the chute behind the chair would be able to dump the bodies directly into the basement without going through the center of Ms. Lovett's shop.

Sweeney Todd: You have a room over the shop, don't you? If times are so hard, why don't you rent it out?
Mrs. Lovett: People think it's haunted.
Sweeney Todd: Haunted?
Mrs. Lovett: Yeah. And who's to say they're wrong? You see, years ago, something happened up there. Something not very nice.
Trivia: Even though they play mother and daughter in this film, Laura Michelle Kelly is only six years older than Jayne Wisener.
More questions & answers from Sweeney Todd
