"[J.F] Kennedy's own accent was inconsistent. So people are inconsistent. And it always kind of irks me when people talk about inconsistent accents, because people are imperfect by nature. So in the end, what you do is, you do an inhabitation and not an imitation."

I also listened to hours and hours and hours and hours and hours of [J.F.] Kennedy, and I sort of built [ accent]. And then I got on set [of 'J.F.Kennedy' movie ] and forgot it.But that's what you want to do. You want it to just be real. And I think authenticity was better than - people always talk about when an accent doesn't work, and the phrase you always hear is, "It was inconsistent."
