Factual error: 6 years in a mask and he's able to keep that lovely babyface with just a little bit of grime, which easily comes off? Of course it would have wrecked the whole story but still...
Factual error: The film is set in the year 1662. Louis is supposed to be in the middle of a war against the Dutch. This is actually not correct. The war against the Dutch didn't begin until 1672.
Factual error: Six years in a mask and Philippe's teeth are in perfect condition. All that time without brushing or flossing, you'd think he'd have lost some teeth or been in wracking pain from toothaches.
Factual error: At the end of the movie, the shot of the castle on the left hand side of the main building, you can see a white or gray car drive by. (02:04:44)
Answer: Both Louis and Philippe are actually D'Artagnan's children. This is why D'Artagnan continues to defend Louis for much of the early part of the film, despite the King's callousness, because he feels that he must defend his son, even against his oldest friends. It's only when he discovers Philippe and realises that he has another son, a humble and decent man, that he's finally able to feel pride as a father and can stand against Louis and his excesses.
