As I recall, it included d'Artagnan apologising for his rudeness in picking three duels in the same day because, if he should die in an early duel, it would be quite inconvenient for his other opponents. Also a scene where they decide to bivouac on the battlefield because it's the only place they're confident they won't be spied on by Richelieu's agents, and at some point they have to interrupt their discussion in order to shove a wall on top of a column of British troops.

Perhaps flawed memory is making this story appear far more epic than it truly was, but I am confused as to why it was felt necessary to include airships to spruce it up. I don't expect I shall be attending, though who knows? Social obligations have made me watch many a film I otherwise would not have.
