I am always fascinated by accents, in real life and in movies and I love to hear people who can switch from one to another. I was most recently very impressed with the Appalachian accents in “Logan Lucky,” especially Daniel Craig.

In this video from Wired, dialect/accent/linguistics expert Erik Singer talks about actors who take on one of the most difficult challenges of all, “ideolects,” not just a regional or class-related accent but the specific way a particular individual speaks, from Steve Jobs and Muhammad Ali to Ray Charles or Jacqueline Kennedy. We know the way these iconic figures sound. It takes a very talented and dedicated actor to get the details so right that we barely notice and can just focus on the performance.
