Cole, who portrayed Tommy Shelby's younger brother from 2013 to 2017, left the show before its final two seasons, despite its growing popularity. He shifted his focus to leading roles and earned the British Independent Film Award for Best Actor in 2018.
Joe revealed to The Times that his struggles with academics and university applications were significant, but his love for drama and theater was a major driving force in his decision to pursue acting.
Beyond Peaky Blinders, Cole has appeared in notable roles on The Bill, Holby City, and Skins. He also paid tribute to his late co-star Helen McCrory, who passed away from breast cancer in 2021 at the age of 52. Helen, known for her role as Aunt Polly, had a profound influence on Joe and others. He remembered her as someone who always kept the cast engaged and positive, and he highlighted her special bond with his younger brother, Finn, who had his first acting role on the show.
