This movie is one of Luis Bunuel's best and my personal favourite. Though it was filmed between Belle de Jour and Tristana, it has more in common with Bunuel's three last movies - Discreet Charm of the bourgeoisie, Phantom of the liberty and That Obscure object of desire. Bunuel is at his surrealistic and atheistic best. Though some moments may make almost anybody laugh, the movie is intended for highly educated audience, preferably familiar with the history of heresies and the Catholic Church - without this kind of knowledge much of film's charm will be missing. Milky Way may be called a road movie in a sense: two main characters are on a pilgrimage to Santiago-de-Compostella and while on their way, also travel through time - Milky Way is unique in the way it handles this time travel.
