One of the most iconic scenes featuring Cillian Murphy in Peaky Blinders was never actually scripted to happen. The moment in question is when Thomas Shelby calmly lights a cigarette in the midst of a tense confrontation, a move that has since become emblematic of his character’s cool, composed demeanor.
In an interview, Murphy revealed that this scene was originally written differently. The script called for a more conventional, aggressive response to the tension. However, during filming, Murphy felt that a subtler approach would better capture Thomas Shelby’s unshakeable confidence and control. Instead of following the script, he instinctively reached for a cigarette and lit it, maintaining eye contact with his adversary the entire time.
The decision to keep this unscripted moment in the final cut was made because it perfectly encapsulated Thomas Shelby’s persona—a man who, no matter the danger, never loses his composure. This small but powerful gesture became a signature move for the character throughout the series, further solidifying Murphy’s portrayal as one of television’s most memorable.
