But the producers of the highly anticipated spin-off have ruled out any chance that The Good Wife's Julianna Margulies will appear in the series.

"We talked to Julianna about the show and her relationship with it and Julianna and we agreed that The Good Wife ended that story," Robert King said.

"It would be kind of weird if she comes in and you see her in the background."

The Good Wife, which aired between 2009 and 2016, focused on Margulies' character Alicia Florrick, the wife of a state attorney whose career was destroyed in a sex and corruption scandal.

The title took its name from the notion of the dutiful wife who, in such scandals, is often seen in US media to stand loyally beside her husband despite his infidelity.

But, King added, the series would reference Alicia and Peter in dialogue, and might also feature other characters from The Good Wife "universe".

"[Alicia and Peter Florrick] are mentioned but I wouldn't say constantly," King said.

"The whole point of the show is to try to treat the world as if it's real and that you might bump into Carrie Preston [who played Elsbeth Tascioni] walking down the hall so we want to keep that alive."

The Good Fight picks up a year after the final episode of The Good Wife and focuses on Christine Baranski's character, Diane Lockhart.

Baranski said she and the show's producer/writers Robert and Michelle King discussed what had transpired since audiences last saw her character.

"We spoke about how she processed all that had happened to her, particularly in those final episodes, and where her life was as the new show began in terms of her marriage, in terms of her position at the firm," Baranski said.

The trailer for the series, which was released today, reveals that Lockhart's planned retirement, however, is derailed by a financial disaster.

"It jumps off from where The Good Wife ended in a very interesting way," she said. "But then it turns very dramatic very quickly, especially for Diane."

King said the new series would not shy away from topical issues.

"[The Good Wife] always tried to be fairly even handed," he said. "One of the things we're looking at in The Good Fight is how the environment changes."

King said the series would touch on the scandal surrounding US president-elect Donald Trump, the riseof false news and "the confusion between what's real and what's not real."

"I think that's particularly interesting in this show, because the legal parts of the show are not really about finding the truth, they are about who tells the best story," King added.

"It's always been about who puts across the bigger lie or the better lie, the more convincing lie, so it kind of plays into what we love."
