There are all kinds of visual codes alerting us to vamps and bad girls, from tiny miniskirts to the western names that Helen’s characters always seem to have. But of all of these, the most concise is the cigarette: a girl who smokes is trouble, plain and simple. In movies of the ’60s and ’70s, like An Evening in Paris and Sharmeelee, when a misguided, misbehaving sister tried to impersonate her seedhi-saadhi twin, the cigarette was the dead giveaway. A cigarette (and a western outfit) provided the first clue that something was up with the wicked version of Nanda in The Train, too. And visual cues aren’t all that say vamp—these days, some vamps even get their own leering theme melodies, like Kuch Kuch Hota Hai’s ‘Miss Braganza, uh-huh!’ or Dil Bole Hadippa’s ‘Hey, Soniya’.
