Katherine Kelly has signed up to "Gentleman Jack".
The ex-"Coronation Street" actress will team up with fellow former cobbles resident Suranne Jones on Sally Wainwright's upcoming eight-part drama, and she is "delighted" to have joined the cast.
Katherine said: "I'm thrilled to be reuniting with Sally once again.
"I know how passionate she is about the life and times of Anne Lister, and I'm delighted to be portraying such a key historical character in Anne Lister's story."
Suranne will star as main character Anne, an industrialist in the 19th century who will return to her ancestral home Shibden Hall after years travelling around the world.
Katherine is to appear as Elizabeth Sutherland, the sister of Anne's intended wife Ann Walker (Sophie Rundle).
What's more, "Fortitude" actress Sofie Grabol has joined the cast as Queen Marie of Denmark, and her scenes will be shot on location in Copenhagen.
She added: "When asked if I would like to play the Queen of Denmark in Sally Wainwright's brand-new series, I could not have said "yes" fast enough!
"I'm excited to welcome the "Gentleman Jack" team to Copenhagen, and to film my scene as Queen Marie with the wonderful Suranne Jones."
Creator, writer, and lead director Sally - who is also behind "Scott & Bailey", "Last Tango in Halifax" and "Happy Valley" - is pleased Katherine and Sofie have signed up for her latest production.
She said: "It's so exciting that Anne Lister's story has attracted such an extraordinary cast, and now we can add to that the unique talents of Katherine Kelly and Sofie Grabol!
"Anne Lister is taking us up to Scotland and across Europe."
Derek Riddell, Veronica Clifford, Sylvia Syms, Brendan Patricks, Caspar Phillipson, Polly Maberly, Lucy Black, Stephanie Hyam and Dino Fetscher are among the other stars set to appear in the drama.
Filming is due to draw to a close in the coming weeks, and the drama will air in 2019.
