Unlike Bunuel's That Obscure Object of Desire, Berlanga pursues a concrete, or more accurately “polyurethane,” object. In a risqué role, French actor Michel Piccoli plays Michel, a Parisian oral surgeon who has an open but frustrated relationship with his wife. His remedy is a life-size sex doll imported from Japan. Slowly Michel's desire becomes devoted exclusively to his pliant plastic partner, who is capable of embodying all forms of fantasy, from newlywed to slutty slave. By turns rapturously absurd and innocently obscene, Tamaño natural is really about the demure dentist's estrangement from things human and fleshy-no deflated egos here.
