The former model, 29, who studied drama at Yale and is known professionally by her middle name, plays heroine Marion Brook
For those on the hunt for a good old costume drama to get your teeth into, there is good news on the horizon.
Filming resumes imminently on The Gilded Age, the lavish new nine-part drama created by Downton Abbey writer Julian Fellowes.
It stars Christine Baranski and Cynthia Nixon as aristocratic siblings who take in their orphaned niece, played by Louisa Jacobson, youngest daughter of Meryl Streep and her husband Don Gummer.
The former model, 29, who studied drama at Yale and is known professionally by her middle name, plays heroine Marion Brook who, in 1882, moves from Pennsylvania to be with her aunts in New York after her father, a Civil War general in the Union army, dies.
