Tropes
- Dawson Casting: In several roles, including his two "breakout" roles in the 2017 films Dunkirk and The Killing of a Sacred Deer, he has played teenagers when well into his twenties. Director Bart Layton was initially hesitant to cast him
as an American college student in American Animals because he thought he looked too young.Bart Layton: I was concerned because he looked so young. I mean, he looks 16 and these guys are in their twenties. And I was already in the process of casting Evan Peters... as the other kinda lead. And Evan’s like 30. And Barry’s 25 but looks young. And I was like how’s that gonna... so I put that aside, but then I kept coming back... - Fake Nationality: While most of his roles tend to match his Irish nationality, Keoghan has often portrayed Americans: (The Killing of a Sacred Deer, American Animals, The Batman and Masters of the Air), Brits: (Dunkirk, The Green Knight, and Saltburn) and even a Ukrainian (Chernobyl).
