Emily Fairn as Anne Plunket (née Guinness)

The Enigmatic Figure: James Norton as Sean Rafferty

One of the most compelling and crucial characters outside the immediate Guinness family is Sean Rafferty, played by the acclaimed British actor James Norton. Rafferty’s character adds a layer of grit and intrigue reminiscent of Knight's previous work on *Peaky Blinders*.

James Norton portrays Sean Rafferty, a character described as the Guinness family’s foreman and "fixer" at the St. James's Gate Brewery. He is a man who has worked for the family for years and understands the inner workings of the brewing operation and the political landscape of Dublin better than the Guinness siblings themselves. His role is not merely that of an employee; he is a key player, often acting as a vicious henchman who becomes entangled in the family's personal and professional dramas, including a complex relationship with one of the Guinness children.

Norton, a BAFTA nominee, has stated that playing the role of Rafferty was "probably the most fun" he has ever had on a set, a testament to the character's complexity and the show's intense narrative. His presence, as a powerful figure from outside the aristocratic circle, serves as a crucial bridge between the family's wealth and the working-class reality of 19th-century Dublin.
