Directed by Luchino Visconti, "Ludwig" is a scrupulously made if talky and overlong spectacle that tries its best to avoid any specific history like the unification of Germany in exchange for an examination of the role of the ruler in a monarchy. In other words, who runs the country: the king or the nobles? And what if the king has little interest in statesmanship?
The movie is told in flashback from a hearing set to determine Ludwig's mental capacity to rule, determining whether he is insane or merely eccentric.(This does remind me of a very recent case where the royal title was only honorary.) I could tell you he is certainly gay. In any case, there is a simple answer located in an old saying: If you are poor, then you are crazy. If you are rich, then you are eccentric.
