My Take
To me, Keir O'Donnell is the kind of character actor who quietly makes a film better. Born in Sydney and trained at a music conservatory, he brings a strange, precise energy to scenes, whether as the unsettling brother in Wedding Crashers or in American Sniper. What impresses me most is his range beyond acting: he writes and produces too. I have a soft spot for performers who understand a project from every angle. He may never chase the spotlight, but craftsmen like him tend to enjoy the longest, most respected careers in the business.
