A second movie that I’d like to point out as having done the heraldry very well (however little the rest of the movie may have had to do with the late Middle Ages!) is A Knight’s Tale. Sure, the armor was wrong, the soundtrack was modern rock music, the Nike "swoosh" as an armorer’s mark was totally 20th Century, and any relationship to actual history was FUBAR, but the heraldry ... well, I’m pretty sure that someone reviewed at least one medieval roll of arms in designing the coats of arms and heraldic shields for this movie.
When I first saw this movie in the theater, as the procession of knights and shield-bearers was marching by in front of the camera, I thought to myself, "Wait a minute! I think I recognize that elephant." I haven’t found enough good stills from the film to double-check the way I’d like to, but I’m pretty sure that at least some of the shields that appear in the film, both borne by some of the knights and decorating the viewer’s gallery at the joust, came from the Zürich Wappenrolle. For example, that elephant that I thought I recognized? Check out the arms of Helfenstein at http://www.vikinganswerlady.com/ZurichRoll/ to see what I thought of when I saw one of the shields in the movie. Was it the arms of Helfenstein that appeared in the movie? I don’t know for certain. I’ve not been able to find a still from the film that shows it. But I’m pretty sure .... And certainly a lot of the other shields that I have been able to find stills of are equally good heraldry.
As a consequence, A Knight’s Tale is high on my (short) list of movies with good heraldry in them, despite it’s entirely non-medieval "feel" and multitude of anachronisms.
