Culture Space discusses Luis Buñuel's 1972 film The Discreet Charm of the Bourgeoisie (1972) (as part of the Avant-Garde Film Blog-a-Thon.)
The friends' attempts to sit down and enjoy a meal are continually interrupted by one absurdist occurrence after another, by the arrival of troops, by the realization that they sitting on a theater stage in front of a live audience, by the intervention of armed gunmen. These all might be the material of individual dreams, which themselves might be parts of a larger dream, but Buñuel deliberately confuses us by interrupting these sequences with scenes that clearly are dreams ... Yet it is the film's rupturing of the symbol of the meal that is most powerful. For the meal, the tea ceremony, the weekend lunch are the central, accepted social rituals of the bourgeoisie, and with their rituals distended, the characters are cast adrift with little sense of purpose or duty. This is why, despite its humorous moments and its status as a comedy, The Discreet Charm of the Bourgeoisie, ultimately, is as disturbing as it is hilarious.
