When a wife says she can smell the whiff of betrayal on a cheating husband, people nod and go “uhm-hmm”…knowing exactly what she means. And people know exactly what Marlene Dietrich meant when she told Fred Zinneman that people could “smell” the fact that From Here To Eternity was a must-see despite there having been no publicity. But people resent others claiming they can smell what a forthcoming movie will probably be like, based on the usual indicators (including the unmistakable whiff of calculated emotional mauling).
