When Ailric leaves his village with young Robin he has only about three arrows in his quiver. When he drops off Robin at the mill and rides away, his quiver is full of arrows.
It changes from mid summer with all the leaves on the trees to autumn with bare branches in between scenes.
As Robin pulls the arrow from Simon de Belleme's body there is a loud popping sound.
During the fight at Castle Belleme on several occasions modern rain pipes are visible.
