After an extensive search, The Carrie Diaries found its leading lady last month, and now the Sex and the City prequel rounds out its cast with the characters that helped turned the small town country girl into the Prada princess.

Former Doctor Who companion Freema Agyeman is trading in her TARDIS keys for ones to the penthouse, by landing a supporting role on The CW’s pilot, The Carrie Diaries. Agyeman will portray young Carrie Bradshaw’s (AnnaSophia Robb) mentor Larissa, who is described as a cool cutting-edge editor for Interview Magazine – an editor who is also not stranger to partying hard. Larissa will help the newly-planted Carrie navigate through ‘80s Manhattan, while helping the budding writer hone her craft.

Should the pilot get a full series commission (which seems probable), the recent casting of Agyeman will set the UK actress up for her North American debut. Although, to American fans of Brit-hits Doctor Who and Torchwood, Aygman is easily recognized as the Doctor’s love-struck companion Martha Jones. Currently, Agyeman stars as crown prosecutor Alesha Phillips in the English adaptation of the Law & Order series, Law & Order: UK. With no official word on the show’s renewal, it’s still up in the air what Freema’s role would be, should Law & Order: UK see a seventh season.

Besides Agyeman, other recent Carrie Diaries cast announcements include relative newcomers Austin Butler (Aliens in the Attic) as the troublesome Sebastian Kydd (Carrie’s main love interest), as well as Brendan Dooling as Walt, her BBF who is struggling to come to terms with his sexuality. Eli Stone co-star Matthew Letscher will portray Carrie’s father, with actresses Katie Findlay (Psych) and Ellen Wong (Scott Pilgrim vs. the World) playing her Pre-Manhattan best girlfriends, Maggie Landers and Jill ‘The Mouse’ Thompson, respectively.

No mention yet if Sex and the City gal pals Miranda, Charlotte or Samantha will make an appearance – but in what is shaping up to be a Smallville for girls, the origin story of Carrie Bradshaw might be altered a bit from Candace Bushnell’s best-selling book to give younger versions of the Sex and the City characters a chance for a cameo. Fans of The Carrie Diaries novel already know that at the end of the book series, a familiar SATC face makes an appearance, adding to the likelihood that writer Amy Harris will work fan-fav characters into the prequel.

Expect the CW’s final word on The Carrie Diaries this May
