Mastering an American accent has become a rite of passage for British and Australian actors, and assorted other former British colonies. It’s an interesting phenomenon: in America we send most of our young actors through the teenybopper homogenizing machine, which spits out enough semi-interchangeable over-coiffed influencers every year to fill Disney Channel sitcoms and country music contracts. The downside of which is that casting directors looking for someone “authentic” looking frequently land on actors born and raised thousands of miles away. Half of our superheroes are English and Australian.
