Catherine Tramell is a fictional character in the 1992 film Basic Instinct and its sequel, Basic Instinct 2. She is played by Sharon Stone in both films. In Basic Instinct, Tramell is the antagonist and love interest of washed-up detective Nick Curran; Basic Instinct 2 pairs her with the similarly troubled British psychologist Michael Glass.
One European critic defined Catherine Tramell as "a mix between the classic femme fatale and the new psycho killers, one of the most evil characters ever created, on Hannibal Lecter's level". She was nominated to be a member of the American Film Institute's "Best Villains" list. She was also included as one of the best 250 fiction villains ever created. In June 2010, Entertainment Weekly named her one of the 100 Greatest Characters of the Last 20 Years
