A Kiss in the Dark (1949)

Snooty concert pianist Eric Phillips is tired and beginning to fear he's losing his talent. His condition is not helped when he discovers he's the owner of an apartment building and the tenants have a long list of grievances. His manager suggests he move into the building for a rest, an idea that initially does not appeal to Eric. He begins to feel differently as he becomes involved in the lives of his eccentric tenants, especially a pretty model named Polly.
