Bird motifs are used throughout the 2010 series in the costumes, paintings decorating the sets, and on china and wallpaper patterns, to echo the bird theme employed in the three episode titles: "The Fledgling", "The Ladybird" and "The Cuckoo".

Unlike the real Eaton Place, the street in Leamington Spa where the Eaton Place exteriors are filmed has houses on one side of the street only (there is a small park on the facing side). For this reason, most shots have to be carefully framed to show one side of the street only. The occasional wide establishing shot is blended in post production with a reverse angle shot of the same row of houses so that the street appears to have houses on both sides.

In August 2011, it was announced that Eileen Atkins (Lady Maud Holland) had decided not to appear in the next series because she was unhappy with the direction the new scripts were taking.
