\'Belgravia\' is set to return for a second series.
The period drama - penned by \'Downton Abbey\' writer Julian Fellowes - proved to be a hit with viewers in the UK and the US, and ITV bosses are looking for a way to revive the show after Julian originally wrote the story as a one-off drama.
A TV insider told The Sun newspaper\'s Bizarre TV column: "\'Belgravia\' got respectable viewing figures when it aired in the UK. But getting a good response in the US is almost as important.
"That is why all those involved with the show are secretly trying to think of a way to create a sequel."
The series set in 19th century London ran for six episodes and starred the likes of Alice Eve, Tamsin Greig, Philip Glenister and Dame Harriet Walter.
However, if there is a new series then it looks as though the current crop of characters will not return, as Julian previously teased another season before the first had aired.
He said: "This is a completed story. We will have to see if anyone wants more.
"We would need a new story with new characters."
Philip previously said his \'Belgravia\' character is based on \'Only Fools and Horses\' wheeler dealer Derek \'Del Boy\' Trotter.
The 57-year-old actor played James Trenchard in the ITV drama, and he said his alter ego is a "cross between Donald Trump and Del Boy" and a "self-made man" trying to elevate himself in society.
He explained: "He\'s a cross between Donald Trump and Del Boy. He\'ll go to the opening of an envelope and sometimes makes a total fool of himself. What I love is his ambition.
"Without Victorians like James Trenchard, we wouldn\'t have a lot of the incredible infrastructure that we have today and take for granted.
"He\'s the son of a market trader, who\'s worked his way up, so he\'s a self-made man. One of the themes of \'Belgravia\' is the beginnings of the nouveau riche and he fits into that bracket."
