Perfume: The Story of a Murderer (2006)

Director:  Tom Tykwer

The premise of Perfume is as perverse as it is intriguing: A man with a heightened sense of smell goes on a maniacal mission to create the perfect scent, which can only be captured by murdering the woman who is unlucky enough to give it off. As the murderer finally bottles the perfume he has labored his entire life to create, he is captured and sentenced to death. 

He rubs a single drop of the perfume on his skin before he faces the crowd that awaits his hanging, but when they catch a wiff of him, they become instantly intoxicated by his scent. The formerly bloodthirsty mob, high on their collective olfactory arousal, declare the killer innocent and the sea of bodies merge together for the most massive orgy imaginable. For sheer immensity (the two minute scene required 750 extras and took five days to shoot), Perfume's climactic scene is a sexual and cinematic triumph.
