Continuity mistake: In the scene where they are all having a farewell dinner at Tony's restaurant, first the spaghetti is in the large bowl with Tony mixing, then suddenly the spaghetti has been dished to to each person's individual bowls.
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).
Other mistake: The two cappucinos that Will brings back to the bookshop, which are then consumed during conversation, are obviously empty cups. The supposedly hot drinks are gone within seconds with no residue on the drinkers' faces.
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.
Continuity mistake: When William visits Anna's movie set near then end, the security guard won't let him pass then when Anna's PA invites him in the security guard has disappeared leaving the entrance completely unattended.
Continuity mistake: After dinner with the perfect girl, they are in the living room and Belle is in her wheelchair. When Max picks her up to take her upstairs she is on the couch.
Continuity mistake: During the final press conference, William is completely covered by journalists in the close-ups, and totally visible in the wide angle. This keeps swapping back and forth.
Continuity mistake: When William is about to jump over the private garden fence, Anna lowers her arm. A frame later, from a different angle, it's up and she's lowering it again.
Continuity mistake: While Bernie asks Anna about her actress' salary, his arm swaps from up to down depending on the angle.
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.
