Barry Keoghan was a young Irish actor whose brooding yet youthful presence brought a unique flavor to some of the 21st century's most acclaimed films. Born on October 17, 1992 in Dublin, Ireland, Keoghan began acting in earnest in 2011, with appearances on the soap opera "Fair City" (RTE One, 1989-) and the short film "Stand Up" (2011). In 2013, Keoghan landed another part on a popular TV drama, playing Wayne, the "heartless cat killer" on "Love/Hate" (RTE, 2010-2014), before making his film breakthrough in Rebecca Daly's drama "Mammal" (2016), for which he received a nomination for Best Actor in a Lead Role - Film at the Irish Film and Television Awards. However, 2017 would prove to be Keoghan's biggest year yet, with important roles in two highly popular and well-regarded films: Christopher Nolan's WWII drama "Dunkirk" (2017), alongside Mark Rylance and Cillian Murphy, and Yorgos Lanthimos's revenge horror "The Killing of a Sacred Deer" (2017), with Colin Farrell and Nicole Kidman.
