This is a subject which strongly recalls Marcel Pagnol's works such as the Cesar/Marius/Fanny trilogy and mainly "Angèle" ;the only difference is that the girl is,although seduced and abandoned ,not pregnant ,perhaps because of the occupation days and the Vichy moral.The Part of the priest -not present in atheist Pagnol's works-is important :not only he comforts poor Auguste ,but he also shows the straight and narrow to Mireille : "you were born to marry and to raise children" ;this moral blames the rich buck whose parents are nothing but parvenus (outstarts) and who has a wild time in the dangerous city of Marseille with hussies.Fernandel is touching as a nice fisherman who grows a rare flower and "does know what it is to love " ,should we believe the girl who is as selfish as she is naive and mindless.When she breaks the flowerpot ,the impatient girl hardly apologizes.A song (about the Lucky star of the title) is featured,not performed by Fernandel.
