The actress, who played Samantha Jones in the HBO series and two movies, spoke to PopEater about the future of the franchise, stating that she is uncertain whether a third instalment will ever be made.
"I don't know if it will happen. I really, really have no idea," Cattrall said. "I love playing Samantha Jones. I would love playing Samantha Jones again, but I don't know if I will."
The 54-year-old went on to open up about her reluctance at making the films in the first place.
"Originally I was asked to do the movie with no script, no start date and a very paltry sum," said Cattrall. "I thought the three of us should fight for a piece of what we created and that was my reluctance."
Cattrall admitted in May that she finds it difficult to lose weight, claiming that her recent diet was "painstaking".
The actress recently said that she enjoys her freedom, stating that the end of Sex and the City has allowed her to take control of her own life.
Cattrall can be seen next in Meet Monica Velour as an aging porn star.
