Rising Damp de la Tour, Richard Beckinsale and Don Warrington. Rossiter played Rupert Rigsby (originally Rooksby in the stage play), the miserly, seedy, and ludicrously self-regarding landlord of a run-down Victorian townhouse who rents out his shabby bedsits to a variety of tenants. Beckinsale played Alan Moore, a long-haired, naive, good-natured and amiable medical student who occupies the top room. Frances de la Tour played Ruth Jones, a fey, whimsical spinster and college administrator who rents another room, with whom Rigsby is in love and to whom he proposes in the last episode. In the pilot episode, a new tenant arrives. Philip
