Barry Keoghan

Keoghan's screen presence first registered widely on Irish television through Love/Hate, the RTÉ crime drama that ran to serious critical acclaim and gave him early exposure to the kind of morally dense material he'd keep returning to (Wikipedia). That foundation matters — it's not nothing to cut your teeth on a show where the writing doesn't let characters off easy. The international breakthrough came fast and came in clusters. Dunkirk (2017), directed by Christopher Nolan, put him inside one of the most technically demanding productions of that year, alongside a cast that included established names from across British and American cinema. Same year, The Killing of a Sacred Deer — Lanthimos's cold, deeply unsettling psychological thriller — gave him the kind of role that gets people in the industry paying attention in a different way. He won the Irish Film and Television Award for Best Supporting Actor for that performance and picked up an Independent Spirit Award nomination for Best Supporting Male (Wikipedia). Two films, one year, two completely different tonal worlds. That's a range statement. Calm with Horses followed, and it's probably the performance that cemented his reputation among people who track this stuff closely. The BAFTA nomination for Best Actor in a Supporting Role (Wikipedia) wasn't a surprise to anyone who'd seen it — he plays a character caught between loyalty and conscience in rural Ireland, and there's a scene where almost nothing is said and yet everything lands. After that, the bigger platforms came calling: Druig in Marvel's Eternals brought him into franchise territory, and his appearance as the Joker in The Batman (Wikipedia) — brief but genuinely unsettling — became one of the more discussed moments of that film's release. He's got a project listed for 2026 that suggests he's not slowing down, though details remain limited in current sourcing.
