Continuity mistake: Ed Harris plays a property manager character and is featured in the beginning of the movie, walking with a pronounced limp, a seemingly painful gait. His character is shown in many other nominal scenes throughout the movie without limping. Most notable, shortly before the end of the movie, his character is shown dancing wildly, spastically, and jumping to music, seemingly unencumbered and fluidly, in a way that his character in the first part of the movie would not have been capable of doing.
Character mistake: When Bianca's mother leaves the room Bianca says "I'll give you three more seconds to come back" and counts on her finger but she counts backwards starting with one finger, then two then three shown as she says "three, two one." She should have shown three fingers, then two and then one. (00:34:35)
