The film that gave most of the world 's moviegoers their first good look at Ms. Deneuve and embedded her clear , strong features in their collective memory -- anyone who saw her then understands exactly how Mr. Depardieu feels in '' Changing Times '' -- was Jacques Demy 's radiantly melancholy '' Umbrellas of Cherbourg '' ( 1964 ) , in which she plays a lovestruck teenage shopgirl who learns she 's pregnant while her boyfriend is off fighting France 's war in Algeria .
