The Cast Of Downton Abbey Become American For A Minute - And It's Really Unsettling

Amazing.

Downton Abbey wouldn't be the same without the posh accents and quintessential Britishness of the cast. So when Michelle Dockery, Hugh Bonneville and Allen Leech were asked to perform a scene in accents from across the pond, the result was rather unsettling.

Appearing on The Late Show With Stephen Colbert, the TV show host tasked the Brits with reading out some classic Downton lines - with an American twang.

'I think part of the appeal for Americans is we hear the accent and we think of it as very classy,' said Stephen, handing them cards with their new lines.

In seconds, the plummy accents were gone, and in their place were accents from all over the USA - though we have to say, Allen Leech's was our favourite.

We're also amazed by how seamlessly the actors were able to transition into Americans - but we guess this is why they're actors at the top of their game, and we're not.
