Hm... Speculating about someone's personal choices or suggesting that they have undergone surgeries without concrete evidence can be misleading and unfair. Actors, like Cillian Murphy, often undergo physical transformations for their roles through the use of makeup, prosthetics, and costume design.
Regarding Cillian Murphy's appearance in different movies, it is worth noting that actors can portray a wide range of characters with varying looks and styles. This includes the use of hair and makeup to create specific aesthetics that align with the character's portrayal. It is not uncommon for actors to look different in different roles due to the artistic choices made by the production team.
Beauty and personal preferences are subjective, and what one person finds attractive may differ from another's perspective.
