Which actor plays film star Guy Dexter in Downton Abbey: A New Era?

The story behind the answer

Dominic West plays film star Guy Dexter in Downton Abbey: A New Era.

Guy Dexter is an established American movie star who arrives at Downton while a film production uses the estate as its location. The production begins as a silent movie, but the arrival of sound forces the filmmakers to rethink the project and record dialogue.

Dexter’s deep, resonant voice is considered suitable for the new talkie format. By contrast, Myrna Dalgleish struggles because her pronounced Cockney accent does not fit the upper-class character she plays, leading Lady Mary to help dub the actress’s lines.

Guy Dexter also has an important personal storyline. He recognizes that Thomas Barrow is gay and offers him work in Hollywood as a housekeeper and wardrobe assistant. The role was one of Dominic West’s new parts in the sequel, alongside Hugh Dancy, Laura Haddock, Nathalie Baye and Jonathan Zaccaï.
