Mein Leopold was based on the long-running play by A. L'Arronge, originally written in the 1870s. Max Adelbert plays a wealthy old Berlin shoe manufacturer who sacrifices all for the sake of his son Leopold (Harald Paulsen). The boy repays his father's devotion by behaving like a thorough bounder, though he eventually redeems himself through the simple expedient of honest hard work. Meanwhile, a trio of subplots involving three young couples are adroitly woven into the central narrative. A delicate blend of comedy, sentimentality and pathos, Mein Leopold proved to be a box-office bonanza.
