The blonde actress, who played maneater Samantha Jones in the hit US TV series, is looking forward to reprising her role in the film version, which was announced this week.
She told Britain's Heart radio station: "I'm really am so flattered because I feel that people actually do miss the show and the characters."
However, Kim admits she had reservations about making a movie version because she was worried about whether the script would live up to expectations.
She added: "I thought the series really ended so well and to re-open it would have to be a great script.
"As with any project that you do it really starts and ends with the script, you've got to ask the questions, 'Who are the characters? Where will they go? What will their journey be? Will people be interested?'
Earlier this week, it was revealed the 'Sex and the City' movie will begin shooting in September.
The much-anticipated film, was given the go-ahead after its four main stars - Sarah Jessica Parker, Cynthia Nixon, Kristin Davis and Kim - all agreed terms.
According to reports, filming will start in September with a release date set for next year.
Speculation has been rife there will be a movie of the show, about four female New Yorkers and their sex lives, ever since it ended in 2004 after six hugely successful series.
