Robert Downey Jr. was set to star but had to drop out when he was charged with drug possession. Kurt Russell was attached at some point but bailed out because he felt uncomfortable with the nudity.

Eventually the production was dropped and the movie canceled. In June 2001, Sharon Stone filed a lawsuit against the movie's producers, Andrew G. Vajna and Mario Kassar, for being responsible for the delays and therefore making her unable to take other jobs. She filed for nearly $100 million in damages. Three years later, during her promotion tour for Catwoman (2004), she stated that she had finally dropped the charges and that Basic Instinct 2: Risk Addiction was back on track. Both Stone and the same producers were still making the film together.
Sharon Stone's lawsuit against producers Andrew G. Vajna and Mario Kassar claiming that she had been promised $14 million, with the assurance that she'd get paid even if the movie never got made. The producers had missed their February 2001 deadline. It was settled out of court in 2004.
