Downton Sixbey: Jimmy Fallon's Miniseries About Studio 6B (VIDEO)

Fans of Jimmy Fallon and "Downton Abbey" better grab your inhalers, because "Late Night" premiered a new segment Thursday night and it bears a striking resemblance to a certain hit BBC series. It's called "Downton Sixbey," and it chronicles all of the things that happen behind the scenes at a late night talk show.

It turns out that NBC's studio 6B isn't quite what you'd expect it to be. Sure, Jimmy may seem like he has an American accent in everything that makes it to air, but backstage he's a proper British gentleman just trying to keep his show in order.

Check out the full clip above (and keep your eyes peeled for the best Maggie Smith impression we've seen yet).
