My Sister Eileen (1942), directed by Alexander Hall.
Rosalind Russell screwball comedy about two sisters trying to make it in New York. Not exactly top-drawer but it has good bits and keeps moving.
Their basement apartment looks like the same set used for A Night to Remember made the same year. Both films had Brian Aherne, who sometimes looks like a less buff Errol Flynn, and Donald MacBride, who made a career playing flustered cops.
Apparently the Code allowed prostitution if referenced comically.
