to everyone asking what the meaning of the video is: both men are metaphors - the dark haired man represents Rita's old life, her true self, while the blond photographer represents the new glamorous life of fame with all its sexy allure and toxic effects. Rita gets seduced by the sexy new life of fame despite the growing protests of her 'inner true self' (e.g. the arguments between the dark haired guy and the photographer). finally she begins to see how the 'new life' can be toxic and that she's losing her true self - but when she tries to turn back, she realises that she can't go back to her old 'true' self either because it has been 'poisoned' as well (when the photographer manages to get to the dark-haired guy at the end). that's what is meant by "poison" =)
