				A floral scent accompanies a love scene, while a mix of peppermint and rosemary is emitted during a tear-jerking scene. Joy is a citrus mix of orange and grapefruit, while anger is enhanced by a herb-like concoction with a hint of eucalyptus and tea tree.

 Somehow, Colin Farrell does not conjur up the wafting scent of eucalyptus and tea tree, somehow beer & cigarettes seem more appropos.  Then again, I keep thinking back to John Waters work with a Smell-O-Vision card.....
