The latest development in the 'Peaky Blinders' saga is the upcoming release of the film 'Peaky Blinders: The Immortal Man,' set to premiere in March 2026. Cillian Murphy, who reprises his role as Tommy Shelby, found revisiting the series emotionally challenging due to the passing of co-star Helen McCrory in 2021. McCrory, who played Polly Gray, was a significant presence in the series, and Murphy described the experience of rewatching her performances as 'quite heartbreaking' (tvline, February 14, 2026). Despite the emotional toll, Murphy emphasized the importance of reconnecting with the series to ensure the film captures the essence of 'Peaky Blinders.' He stated, 'You can't just switch him on and off... it takes a few weeks to get back to it,' highlighting the depth of his commitment to the role (tvline).
