"Luis Buñuel's The Phantom of Liberty was quickly dismissed upon its release in 1974. Not only did it have to contend with the lingering success of 1972's similarly themed but significantly less abstract The Discreet Charm of the Bourgeoisie, but it was quickly followed by the dreamlike, bi–polar romantic entanglement of the director's last film, That Obscure Object of Desire. Like Discreet Charm, the plot–free Phantom of Liberty is a patchwork of comedic sketches and sight gags through which Buñuel ravages a complacent European culture and the various sexual hang–ups and historical and cultural disconnects of its inhabitants. This heady, almost off–putting masterwork isn't particularly easy to decipher (maybe we aren't meant to), which is why it's best to approach it as a literal comedy of manners.
Films structured around daisy chains of dysfunction are a dime a dozen; most, though, are as tiresomely long–winded as they are content with their own strained circularity. This isn't the case with Phantom of Liberty, which begins with a shot of Goya's 1808 masterpiece 'The Third of May.' The painting depicts Napoleon's army executing a group of faceless Spaniards, and via a reenactment of this struggle, Buñuel depicts how one of Napoleon's captains tries to defile the monument of Doña Elvira only to be smacked on the head by the moving arm of the statue of the woman's husband. (He later intends to sleep with the woman's corpse, and when he opens her coffin, he's amazed by how her beauty has been preserved.) It's the first of many sight gags in the film, each and every one as startling as they are perversely funny. All these moments are possessed by a sense of shocked wonderment and discovery, and they all more or less evoke fragile pasts and characters trying to reconcile their historical detachments."

"if the energetic machine expressed the disciplinary bourgeoise society of the 18th and 19th centuries, computers, electronic and cybernetic machines express what Deleuze calls the 'society of control.'"
