When Julian Fellowes offered his hit ITV series Downton Abbey to the US network NBC he was told American audiences would never sit through an Edwardian-era period drama.
But the broadcaster has had a change of heart after US viewers fell for the series and now Fellowes is to create an American Downton for NBC, set in 19th-century New York.
Three years after sending the Oscar-winning screenwriter packing, NBC has asked Fellowes to put an American twist on the British show, which has won six Emmy awards and achieved record ratings when screened by the Public Broadcasting Service.
The new show, whose working title is The Gilded Age, will be set in New York City in the 1880s and focus on the rising, and inevitably plunging, fortunes of the princes of the American Renaissance.
Fellowes, the executive producer, said: "This was a vivid time, with dizzying, brilliant ascents and calamitous falls, of record-breaking ostentation and savage rivalry; a time when money was king."
