This is what the article has to say on Hannibal Lecter.
Perhaps the most famous and ≪ caricatured ≫ example of this type of psychopath is that of the cannibalistic psychiatrist Dr. Hannibal Lecter, as portrayed by Anthony Hopkins in the acclaimed, Academy Award-winning 1991 film The Silence of the Lambs. As portrayed by Hopkins and imagined by Harris (23), Lecter is an exceptionally intelligent sophisticated socialite, whose disarming charisma, erudition, civility, and wit disguise his true nature as a psychopath who murders people and makes gourmet cuisine out of their flesh. Hannibal Lecter, while the embodiment of evil, is also an extraordinarily astute clinician who can diagnose Jodie Foster’s psychological conflicts by identifying her perfume and assessing her shoes and clothing with Holmesian accuracy. He also seems to be invulnerable. Again, Dr. Lecter accumulates many personal characteristics that are not generally found in everyday clinical practice.
(emphasis mine)
Not an everyday or super-realistic psychopath it seems~~ Then again, one of the best movie characters, for sure.
