This is a very funny segment Stephen Colbert did a couple of years ago when three actors from Downton Abbey were guests on his show -- Michelle Dockery, Hugh Bonneville and Allen Leech. Colbert suggests that one reason the show works so well for American audiences is because the high-toned British accents sound SO classy. So he brings out pages of a scene and asks them to do it with American accents.
Usually such things are set up beforehand, and this may have been. But from their reactions, I get the sense that they maybe were only told part of what might happen, but not all. And regardless of what they knew beforehand, the result -- which could have been a quick laugh and that's it -- actually is a bit of a hoot.
