This new special reveals the secrets of the long-running sitcom's extraordinary success. Helped by former cast and crew members, families of the stars no longer with us, and celebrity fans, we learn the secrets of this comedy classic and get to see previously unseen interviews and rare behind-the-scenes archive footage.

Keeping Up Appearances remains one of Britain's best loved series. Running for 5 years throughout the 90s, millions of viewers tuned in to watch the delightfully monstrous Hyacinth Bucket (pronounced Bouquet) as she attempted to climb the social ladder, only to be endlessly let down by her family. In this 90-minute celebration we feature the very best and most hilarious moments from the series, and cast, crew and celebrity fans pay tribute to the show and share backstage secrets. Featuring an exclusive interview with Dame Patricia Routledge, who shares her memories of the show, we learn how she came to be cast, how she developed the character, and what happened when the cameras stop rolling.
