Dominic West is joining the cast of the new Downton Abbey film.

Few details about his role have been revealed, but according to Baz Bamigboye he’ll be playing an aristocrat who arrives as a guest of Lord Grantham.

West will be co-starring alongside Imelda Staunton, who’ll be playing his mum in the next season of The Crown. He’s expected to play Prince Charles opposite her Queen Elizabeth II.

Filming on the new movie is set to begin this spring. The fantastic news for Downton fans is that Maggie Smith will be back as the Dowager Countess – fans weren’t sure if we’d see her again after the events of the first film.
