40+ Famous Actors Who Guest-Starred in 'Sex and the City'
Elizabeth Banks – Season 3
She's now a major movie star, but when Elizabeth Banks appeared in Sex and the City, it was one of her first-ever TV roles. In season three, episode four, Banks' character gives Charlotte the idea for a used dates party. This is because Charlotte had her eye on a politician at a party, only to find out he was engaged to Banks' pearl-wearing Catherine.
Elsewhere in this episode, Miranda decides if she'll go steady with Steve, and Carrie is dating John Slattery's politician character.
Candice Bergen - Season 6
When Carrie brought a character played by actor Wallace Shawn to a party in season six, it was to meet her Vogue editor, Enid. Played by Candice Bergen, the character appeared across various seasons and reprised her role in the first Sex and the City movie.

Interestingly, while Candice Bergen merely acted as an editor at Vogue, her real-life daughter Chloe later became a social editor at the famed fashion mag. The multi-award-winning actress was the perfect fit for SATC's high fashion world.
