Coming Up Rosie (1975)

This situation comedy, produced for children, portrays the misadventures of offbeat tenants in an office building. Among them is Rosie, founder of Zonk Productions, a low-budget film production service. Rosie's partner, an English actor named Dudley, joins her in her often afoul projects. The fanciful, naive, rather inept Dwayne is the building's elevator operator. Two other tenants are Ralph, a slick door salesman, and Myrna, a scatterbrained caterer.
