With filming underway in Liverpool, BritBox has officially revealed more potential suspects filling out Hercule’s six-part first set of cases. Edward Bluemel’s legendary detective will be surrounded by a stacked slate of actors, including Jessica Alexander, who’s coming off a recent starring turn in Ryan Murphy’s new FX body horror series The Beauty, which premiered back in January, alongside Black Sails actor Toby Stephens and Rivals star Katherine Parkinson. Also joining them are Honor Swinton Byrne, Omari Douglas, Paul Forman, Arthur Hughes, Ralf Little, River Medway, and Natalie Quarry. The latest additions build on an already extensive cast that features two Game of Thrones universe alumni in Jack Gleeson and Henry Ashton, among many others.
