Cillian Murphy was born on 25 May 1976 in Douglas, Cork, Ireland. He is a Gemini — mutable air, ruled by Mercury. American and British audiences know him as Scarecrow in Batman Begins, Tommy Shelby in Peaky Blinders, and J. Robert Oppenheimer in Christopher Nolan’s Oppenheimer. This USA and UK profile uses a public birthday. It does not invent a rising sign.

Early life and two crafts
Murphy trained first as a musician. Law school lasted a short time. Theatre in Cork and then London came next. Gemini is the sign of adjacent rooms: two languages, two jobs, two versions of the same face. 28 Days Later (2002) made him a face in UK cinemas and US genre fandom. The Nolan Batman films put him inside a global franchise without making him the poster. Peaky Blinders, a BBC show that became an American streaming event, gave him a decade-long accent and a moral problem.
Career timeline
2002: 28 Days Later. 2005 to 2012: Batman Begins and The Dark Knight as Dr Jonathan Crane, plus The Wind That Shakes the Barley. 2013 to 2022: Peaky Blinders across six series. 2017: Dunkirk. 2023: Oppenheimer. The Best Actor Oscar followed in 2024. 2024 and 2025: Small Things Like These and Steve, quieter films after the IMAX year.
Mercury stories are about range and speech. Oppenheimer is a Mercury film in the old sense: talk as action. Peaky Blinders is Mercury with a razor. The same actor holds both. Compare him with Tom Holland’s Gemini public warmth. Same sign, different temperature.
Gemini traits and how the sign shows up
A low-interview public manner that still sounds precise. Reluctance to live in Los Angeles as a brand. Movement between Hollywood scale and Irish or British intimacy. Strengths: versatility, verbal control, a change of register inside one scene. Challenges: being asked to repeat Tommy Shelby forever, leaving a room before the industry has finished naming you.
Magazine Gemini is twins and text messages. Working Gemini is a change of register inside one job. Mutable air needs a craft or it becomes noise. His craft is preparation that does not advertise itself. If you share the sign, the lesson is not “be two people.” It is “let the work have more than one room.”
Love, luck, USA and UK
He has been married to the artist Yvonne McGuinness since 2004 and has kept the household out of the merch cycle. Gemini is often sold as unfaithful air. The public record here is a long partnership and a career that travels while the base stays put. See our compatibility guide.
