(at around 18 mins) When Emma drags her oxygen cart up the front stairs of the Bates' house, the dramatic camera angle takes in the full width of the house, and it appears extremely narrow. Given that the front door is about 3 feet wide, the whole house is clearly less than 25 feet wide. There is also a long shot of the house in the previews, and we can see that the house is actually wider than it is deep. And yet there are in-door shots showing rooms that are much larger than this.
Emma and Norman refer to written number 4 as English number. The correct term is Arabic numerals, which are also used by the Chinese.
Norman: "It's just a number."
Emma: "In English. Everything else in here is in Chinese."
