Cillian Murphy has quietly become one of Hollywood’s most reliable and bankable actors, known for slipping effortlessly into a wide range of roles. His versatility allows him to play everything from intense leading men to complex, morally ambiguous characters. Hence, it is no surprise that he is drawn to nuanced villains, too, finding them rewarding to play. As the Irish actor himself puts it, layered characters are a ball to enact if they are fully alive on screen.

Cillian Murphy welcomes playing the bad guy, but only when the part is well-crafted, turning the job into a playground for him.

In a July 2023 interview with The Guardian, just before Oppenheimer’s release, Cillian Murphy spoke about his unreservedness in taking on complex characters, some of which could also veer into villainous territory. He emphasized, though, that such roles must be well written, reflecting all shades of the character’s personality, so he can bring depth to parts audiences might otherwise dismiss. “Villains are good,” the actor said at the time, adding that if writers rely on a single trope of any figure, “then they are dull.”

Although Cillian Murphy did not explicitly state he was referring to J. Robert Oppenheimer when discussing villains with multiple shades in The Guardian interview, his thoughts could be linked to the same. The very revered physicist nearly poisoned his Cambridge tutor in 1956 due to complicated feelings, an act classified as attempted murder. Oppenheimer’s past actions serve as a reminder that his character was far from simple, aligning perfectly with Murphy’s description. And while Oppenheimer was not exactly portrayed as a villain in the Christopher Nolan-directed offering, Murphy had played a darker, twisted role in 2005.

Whether he is playing a historical figure or a straight-up villain, he brings depth, subtlety, and a touch of unpredictability to every role.
