Lucy Halliday confirmed to lead The Testaments
As reported by Variety on March 3, 2025, Lucy Halliday will portray the character of Daisy in The Testaments, a project being developed by Hulu as a direct sequel to The Handmaid’s Tale. Daisy is one of the three young women featured in Atwood’s novel. She grows up in Canada and remains oblivious to her roots in Gilead until her life transforms due to emerging political occurrences.
Halliday will be featured with Chase Infiniti, who takes on the role of Agnes, and Ann Dowd, who reprises her character Aunt Lydia. The narrative takes place 15 years after The Handmaid’s Tale, focusing on the viewpoints of these three characters, consistent with the framework of Atwood’s 2019 book.
Halliday is somewhat new to the industry but garnered attention for her role in the 2022 British movie Blue Jean, in which she portrayed Lois. The performance secured her a Scottish BAFTA Award for Best Actress and a British Independent Film Award nomination. She is also scheduled to appear in California Schemin’, the first film directed by James McAvoy.
The Hollywood Reporter also confirmed Halliday’s casting and added that showrunner Bruce Miller stepped back from The Handmaid’s Tale's final season to focus on The Testaments' development. He continues to serve as an executive producer alongside Warren Littlefield and Steve Stark.
The Testaments adaptation will follow Atwood’s narrative timeline

The Testaments will follow the events of Atwood’s novel, which is structured around the perspectives of three characters: Daisy, Agnes, and Aunt Lydia. With Halliday confirmed as Daisy, the casting for the other two central roles, Agnes and Aunt Lydia, has now been confirmed, with Chase Infiniti set to portray Agnes and Ann Dowd reprising her iconic role as Aunt Lydia.
The story is set in a time when Gilead’s control is weakening, and resistance is growing both internally and externally. Daisy’s arc involves learning the truth about her identity and ties to Gilead’s elite. The show is positioned as a standalone continuation but retains core thematic links to the original series. The team behind the production includes executive producers Bruce Miller, Warren Littlefield, and Elisabeth Moss.
