The musical was apparently shot at two takes at least. This led to several mistakes in continuity: Joan's eyes are open/closed when angels are giving her armory; Beaudricourt's servant turns away from him twice and so on.
When Beaudricourt's aide dies, St. Catherine is seen on the right side of stage, pointing at him with her right hand. In the next shor she stands on the left side, pointing with her left hand and then she is on the right side again as she leaves.
Joan's hands during "Road to Vaucouleurs".
During "The Battles" scene, the King is heard talking, but we can see him singing with the others.
At the beginning of "When Death is" scene, a woman is seen in the background singing. But only voices of La Hire and a soldier are heard.
