Downton Abbey - Series 3 - Julian Fellowes Interview

Question: Last season was considerably darker with the war, but now there is an impending marriage. Would you classify this season as a little brighter and more cheerful, or is it just as dark?

JULIAN FELLOWES: We like a few laughs. This season is about the recovery from the war. The war brought a tremendous disruption to England and took many, many families, of all sorts. There were those few years when people were trying to decide if the world was going to go back and be the same as it was before, or had it changed completely, and that’s really the theme of the series. There are chills and spills involved in that, for all the characters, with some laughs and some tears.
