Trivia: Virtually all of the extras who play soldiers in the film were members of Civil War Re-enactor groups who not only freely donated their time but also supplied their own uniforms and equipment.

Trivia: The scene with the hinge-maker almost getting shot has a hidden meaning, when several guns that are used misfire.

The prisoners manufacturing the guns were known to file down the hammer on the pistols so that they would not fire properly, in an effort to thwart the Nazi regime.
Trivia: Paul McGann plays both Girard (the man out to revenge his sister's honor) and the Cardinal's Guard who is killed by D'Artagnan out by the city ruins.
