The Crawley family is back. It’s the 1930s and modernity is threatening the household’s old order. The estate’s finances are as shaky as ever and Lady Mary’s divorce becomes a national scandal, putting her position and reputation on the line. Simon Curtis has returned to direct, Julian Fellowes wrote the screenplay, and Hugh Bonneville, Jim Carter, Michelle Dockery (Lady Mary), Elizabeth McGovern, and the rest of the original cast have reunited—joined by Paul Giamatti as Cora’s American brother. —Elena Clavarino
