It was written by Dick Fiddy and Mark Wallington , and was produced and directed by Harold Snoad , who also produced and directed Keeping Up Appearances .  - Keeping Up Appearances is a British sitcom created and written by Roy Clarke for the BBC, centred on the life of eccentric and snobbish middle class social climber Hyacinth Bucket, who insists that her surname is pronounced "Bouquet". The sitcom follows Hyacinth in her attempts to prove her social superiority and to gain standing with those she considers upper class; attempts that are constantly hampered by her decidedly lower class extended family whom she desperately seeks to hide. Much of the humour comes from the culture clash between Hyacinth's vision of herself and the reality of her working class background, plus the farcical situations she finds herself in as she battles to protect her social credibility.  - An actor (or actress for females; see terminology) is a person who portrays a character in a performance.
