@richardwinston8: Fun fact: Cillian Murphy has admitted that one of the hardest things for him to do as an actor is fake laugh on camera. Known for his intense performances and serious onscreen presence, Murphy once explained that pretending to laugh feels incredibly unnatural to him. Fans of Peaky Blinders may have noticed that Tommy Shelby rarely laughs throughout the series and that's partly because Murphy finds those moments more challenging than dramatic scenes. Ironically, when Tommy does laugh, the awkwardness actually works in the character's favor. The restrained and uncomfortable nature of those moments perfectly matches Tommy's cold, guarded personality, making the performance feel even more authentic. Sometimes an actor's biggest challenge ends up becoming one of a character's most defining traits.
