Nixon played feisty lawyer Miranda in Sex and the City
Sex and the City star Cynthia Nixon is to appear in the ITV follow-up to 1970s drama The Naked Civil Servant.
Nixon, who played Miranda in the comedy series and film adaptation, will play artist and playwright Penny Arcade in An Englishman in New York.
John Hurt reprises his role as Quentin Crisp in the drama, which is being filmed in New York and picks up where The Naked Civil Servant left off.
An Englishman in New York is set to be broadcast next year.
Nixon's character Arcade was a close friend of the Crisp and the two created the long-running The Last Will and Testament of Quentin Crisp.
The ITV1 drama will also feature US actors Denis O'Hare as magazine editor Phillip Steele and Pushing Daisies star Swoosie Kurtz, who plays Crisp's US agent, Connie Clausen.
Executive producer James Burstall said: "Choosing to shoot the film in New York was a risky decision as the drama industry works very differently in the US from the UK.
Quentin Crisp wrote The Naked Civil Servant
"But the huge amount of strategic planning and the leap of faith are delivering a first rate calibre of cast.
There is a real buzz about the project in Manhattan as Quentin was a much loved and notorious figure - everyone has an anecdote to tell about him.
"And we've been touched by the number of friends and admirers of his who have wanted to help with the project in myriad different ways."
ITV drama director Laura Mackie said: "We are delighted to be making another film about Quentin Crisp given The Naked Civil Servant was such a landmark film for ITV.
"It's a real thrill and honour to be bringing an actor of John Hurt's stature back to the channel to reprise such an iconic role.
"This is largely down to the quality of Brian Fillis' wonderful script, which completely captures the extraordinary and outrageous character of Quentin Crisp."
