Magic Casements is the seventh episode of the First Series of the UK Period drama, Upstairs, Downstairs. The episode was written by John Hawkesworth and directed by Joan Kemp-Welch. The episode focused on the possible derailing and eventual survival of the Bellamy marriage. The episode was also notable as it was the first episode filmed in color after the settlement of the technician's strike that paralyzed London Weekend Television and its other Independent Broadcasting Authority (now known as ITV) subsidiaries (the first six episodes of the first season were filmed in black and white).
