The History of Sex in Cinema

In director Anton Corbijn's slow-moving yet taut, stylistic espionage crime thriller/drama (more an existential retro-Euro arthouse film with only three action sequences), George Clooney starred as wary and brooding hired American assassin Jack/Edward. He was hiding out in a rustic, mountainside area called Abruzzo in Italy after a brutal assignment in snowy Sweden required him to kill (with a shot to the back of the head) his innocent, post-coital Swede companion Ingrid (Irina Bjorklund).
In the town of Castel del Monte, where he posed as a photographer and read butterfly guide-manuals, the laconic arms expert's next and "last job" for his ominous boss Pavel (Johan Leysen) was to construct a custom-made, untraceable high-speed rifle (to the sounds of the Madame Butterfly opera) for lethal female Belgian assassin/blonde beauty Mathilde (Thekla Reuten).
He hesitantly engaged in a relationship with often-nude, voluptuous 'heart-of-gold' prostitute Clara (Violante Placido in her first English-language role), although he was cautioned to not make friends with anyone. Paying for her services, he offered her oral sex (off-screen) before they had sex, and she went skinny-dipping (in transparent panties) while picnicking - when he wrongly suspected that she was working with pursuing gunmen.
