Sundance TV and ITV are teaming up to co-produce “Liar,” a six-part thriller starring Joanne Froggatt and Ioan Gruffudd. The miniseries hails from BAFTA- and Golden Globe-nominated producers and screenwriters Harry and Jack Williams and their company Two Brothers Pictures.

“Liar” stars Froggatt (“Downton Abbey”) and Gruffudd (“Fantastic Four”) as Laura Newell and Andrew Ellis, whose initial attraction leads to a date and to far-reaching consequences for each other and their families.

“‘Liar’ is that rare combination of a thoughtful and emotional exploration of the human condition, and a page turner. The Williams Brothers have created something both relevant and compelling, attributes that the SundanceTV audience respect and embrace,” said Joel Stillerman, president of original programming and development for AMC and SundanceTV.

Harry and Jack Williams (“Fleabag,” “The Missing,” “One of Us”) will executive produce with James Strong, who will serve as lead director. Polly Hill, head of drama for ITV, will oversee production for the U.K. broadcaster. Eliza Mellor (“The Living and the Dead,” “Poldark,” “Death Comes to Pemberley”) will serve as producer. Sam Donovan (“Humans,” “The Living and the Dead,” “Utopia”) will direct the fourth, fifth, and sixth episodes.

“I am so delighted to have arrived at ITV and to be working with Jack and Harry Williams on ‘Liar,’” said Polly. “They are brilliant storytellers, who have written a gripping thriller that doesn’t shy away from exploring a powerful subject. I’m thrilled we’ve commissioned ‘Liar’ for ITV and secured such a terrific cast.”

The deal between Sundance TV and ITV was negotiated by All3Media International, which will handle the series’ international sales. Filming is set to begin in November in London and Kent.

Correction: A previous version of this story incorrectly referred to the show as “Liars”; its correct name is singular, “Liar.”
