One of the elements of the Robin Hood legend since the fifteenth century is that he was betrayed and killed by the Abbess of Kirklees Priory.

This movie, for the first time, makes Marian the Abbess, and in a twist on the legend, she kills Robin to keep him from having to live out his life as a cripple, and not for the reward.
