It's time to return to Downton Abbey and your official tour guide will be Derek Hough!

In anticipation of the theatrical release of the Downton Abbey movie, NBC is airing a one-hour special titled Return to Downton Abbey: A Grand Event. The special will be hosted by Derek Hough, who will show viewers an inside look at the film and feature interviews with the cast. The special was, of course, filmed in Highclere Castle in England, the main filming location for Downton Abbey, and it will air Thursday, Sept. 19, one day before the movie premieres.

Though there's no confirmation about which cast members will be featured in the special, you can probably bet that several members of the main cast — including Michelle Dockery, Joanne Froggatt, Maggie Smith, Hugh Bonneville, Laura Carmichael, Allen Leeche, Elizabeth McGovern, Jim Carter, and Matthew Goode — will likely participate, seeing as they all returned for the film.

The Downton Abbey movie will hit American theaters Friday, Sept. 20. The series is currently streaming on Amazon Prime.

Return to Downton Abbey: A Grand Event will air Thursday, Sept. 19 at 8/7c on NBC.
