In anticipation of the September 2019 premiere of the Downton Abbey feature film, this special is a nostalgic celebration of all aspects of the most successful British drama ever - the stellar cast, superb writing, spectacular locations, and dazzling costumes. Planned participants include Lesley Nicol (Mrs. Patmore); Phyllis Logan (Mrs. Hughes); Harry Hadden-Paton (Bertie, Edith's husband); producers Gareth Neame and Liz Trubridge. Pre-recorded interviews with host Deborah Roberts and Julian Fellowes (writer) and Hugh Bonneville (Robert Crawley).
