At 1 hour and 3 minutes, when the two peasants are trying to mime a message to the princess (whom they think is mute), you can see the shadow of a crew member's arm moving quickly in the lower left hand corner of the frame.
In the opening sequence the two villagers see a soldier killed by cavalry. Within moments the soldier is stiffened with a hand in the air, despite the fact that it takes hours for rigor mortis to set in.
During the opening scene, A soldier is being chased then killed by opposing soldiers on horseback. Ah he lays on the ground mortally wounded , and paralyzed in shock and pain, The soldiers on horseback spin and return back. As the first horse passes close by the soldier (for framing effect no doubt) you can see the rider attempting to rein back and to the right to slow the horse to avoid and barely misses the soldier on the ground. The following horse is not as restrained and kicks the soldier in the left ear area with his rear left leg. The soldier on the ground visibly reacts to getting kicked by reaching for his head for a split second before remaining in character for the rest of the shot.
