In the final season of Peaky Blinders, the absence of the character Polly Gray, played by Helen McCrory, was addressed due to the unfortunate passing of the actress from breast cancer in April 2021. The storyline had to be rewritten, and numerous scenes were re-shot to accommodate this change. In the show, it was implied that Polly was murdered, and her absence was depicted through emotional scenes with the characters mourning her. The writer of the show was informed to cut down her role in Season 6, and eventually, she was written off due to her inability to continue with the role. This decision was made following Helen McCrorys passing, and the first scenes of the season were emotional, with the characters mourning her, reflecting the real-life loss of the actress.
