Daniel Day-Lewis’ natural speaking voice is a lot like The Loch Ness Monster or Bigfoot. All are believed to exist while NEVER having been documented. OK….. That’s not really true. We have heard him speak when accepting awards (which happens a LOT) in what, I would assume is his natural voice. He speaks with an English accent in a soft, unintimidating way that is refreshing because we’ve never heard it in any film he’s made. From MY LEFT FOOT (1989) to LINCOLN (2012), Day-Lewis has used a slew of different voices and accents. He’s been Irish, Northern Irish, Scottish, Italian and 3 kinds of American that were believed to have been lost to history. Day-Lewis is the most infamous method actor in the world and does not break character during the entire duration of filming; on OR off set. Do you realize what this means? No actor who has worked with Daniel Day-Lewis has ever heard his real voice — the entire time they worked together. If he didn’t have to come out of seclusion every now and then to accept an Oscar, we would have no idea what he really sounds like.
