Incorrectly regarded as goofs: Multiple differences between the movie and its original source material. Changes made when another medium is adapted into a movie are, by policy, not considered goofs. The movie even begins with a disclaimer that "artistic and historical license have been taken".
Continuity: When Joseph is in prison during the rain scene, he is wearing a white kilt, but when the camera is zooming out through the opening of the cell, he is wearing a red kilt.
