Around the World in 80 Days (2004)

Deliberate mistake: When Prince Hapi says that Monique should be his seventh wife, she says "you have seven wives?" and he confirms. Actually if she is supposed to be his seventh wife he only has got six wives by now.

Passepartout: I'm your new valet.
Phileas Fogg: Uh... I must commend the valet service on their impeccable foresight. But they know I only accept French valets.
Passepartout: Yes. Oh! Oui! Oui! I come from a long line of French valets. On my father's side. Very, very French.
Phileas Fogg: But your accent.
Passepartout: My father French. Never speak. My mother Chinese and never shuts up. All the children pick up her accent.

Trivia: This film was supposed to be Steve Coogan's ticket to Hollywood stardom, but it was not to be. The film tanked at the box office, losing almost US$80,000,000. This is the biggest loss by any independent film ever, and it bankrupted its producers.

Question: When Passepartout, Phileas Fogg and Monique are looking at a map to find a way of avoiding the British police, Phileas notes that they can't go to Singapore or Hong Kong because they're both British Colonies. Monique asks if England owns every country in Asia, Passepartout says they don't own China. Since Hong Kong is located in China, shouldn't England own that as well?
