Corrected entry: Musketeers were the elite shock troops of the King's army, armed with costly muskets. Strange that not one of them actually had a musket, let alone fired one. They only had a few pistols.
Corrected entry: In the scene where Mena Suvari jumps in front of the Queen of England to block the shot fired by the evil man in black, she is hit in the left shoulder. The camera looks at the spot, and D'Artagnan and the Queen both examine the spot. Yet at the end of the movie, she (Mena Suvari) is sporting an arm sling on her right arm. And that's aside from the fact that in those times a bullet to the shoulder would almost certainly have killed you.
