The transformation of non-smoker to smoker is rife with parallels to the transformation of human to vampire:
1) The introduction of an unnatural substance into the body changes the body into something unnatural.
2) The introduction of an unnatural substance into the body results in a craving that suggests the sexual.
3) The introduction of an unnatural substance into the body results in a permanent change in Identity.
As well as...
4) Death is a potently erotic reflection of Life.
5) The deep connections between blood / pulse and air (smoke) / breath.
6) Oral implications / consumption implications.
And of course...
7) The Seduction of Evil.
Oh my...Yes, Yes, Yes...
BTW, I'm a huge fan of the first three novels of Anne Rice's "Vampire Chronicles" - Interview With The Vampire, The Vampire Lestat, and The Queen of The Damned.
However, I can not encourage anyone strongly enough to avoid the fourth novel, The Tale of The Body Thief, which extends the narrative into some rather poorly chosen realms, IMHO, as well as the film adaptation of Interview With The Vampire, which Tom Cruise absolutely destroyed, IMHO. The subsequent film adaptation of The Queen of The Damned suffers from some narrative compression / editing issues, and some embarrassingly bad acting by Aaliyah IMHO, but the rest of the cast, as well as the cinematography and design, are quite good, Stuart Townsend is wonderful as Lestat, and Marguerite Moreau is fantastic as Jesse, a female version of a male character from the original novel.
Another great vampire film (although strangely lacking fangs) is the classic The Hunger, with the very, very, very sexy Catherine Deneuve, who also smokes in a very erotic way throughout.
