That's Gratitude(1934)

Overview

Fly-by-night stage producer Bob Grant inadvertently saves the life of small-towner Thomas Maxwell. The grateful Maxwell invites Grant to move in with his family, which he does, rapidly wearing out his welcome. Finally booted out of the Maxwell household, Grant takes Tom's homely but sweet-voiced daughter Dora with him, giving her a cosmetic makeover and turning her into a big star -- and thereby repaying his host's kindness in a most roundabout fashion.
