In the following sequence (the competition for the brownie), she is wearing the necklace and no hat. (00:38:00)

Then when Anna is standing near the window, we see that there are completely different kinds of books on the top shelf now. (01:39:10)
Continuity mistake: In the scene just before Anna goes into the bookshop with the painting there is an outside shot of the building. In front of the school you can see the woman kneeling down in front of a child but also if you look through the window and door of the shop you can see Will walking in wearing a blue shirt. In the very next scene he is sitting at his desk wearing a pink shirt. (01:39:15)

Continuity mistake: Anyone familiar with Notting Hill will know that the rooftop terrace scenes with Spike and William and later with William and Anna, were not remotely in the same neighbourhood as William's flat with the infamous Blue Door. The rooftop scenes were filmed most likely on rooftop between Ladbroke Grove and Stanley Gardens, while the flat with the Blue Door is located on Westbourne Park Road.
Continuity mistake: The guy that steals a book has his hair either combed or messy depending on the angle.
Continuity mistake: In the scene just after Anna opens the door and all the photographers are outside, Spike walks to the front door in his grey underwear. Just before he opens the door the underwear is covering only one butt cheek (his left). The next shot outside the house the underwear is adjusted and covers both butt cheeks but then when he enters the house and is checking himself out in the mirror, his butt cheek is exposed again.
Continuity mistake: The spring closing the front door when Anna first enters the flat (orange juice scene) is upside down when she next enters the flat (escaping the journalists).
Continuity mistake: When Anna went to the bathroom to change after Will bumps into her, the bathroom is on the third floor. But when Spike walks in to the bathroom when Anna is in the bath, it is on the second floor at the top of the stairs.
Answer: Uncredited actor Taylor Murphy asks "are the two of you getting married?" under the Elvis Costello song, "She." The side of William's refrigerator has a set of magnetized words, found on many refrigerators, which can be arranged and rearranged to form messages for communication to other members of the household, or created just for fun.
