Soon after wrapping principal photography, Ernst Lubitsch talked to the New York Sun in January 1940. "It's not a big picture, just a quiet little story that seemed to have some charm. It didn't cost very much, for such a cast, under $500,000. It was made in twenty-eight days. I hope it has some charm."
To make sure his film was stripped of the glamor usually associated with him, Lubitsch went to such lengths as ordering that a dress Sullavan had purchased off the rack for $1.98 be left in the sun to bleach and altered to fit poorly.
According to the Book "Ernst Lubitsch: Laughter in Paradise", 'The Shop Around the Corner' is the most meaningful tribute possible to the owner and employees of the long vanished Berlin clothing firm of S. Lubitsch.
While directing this movie, Ernst Lubitsch drew upon his extensive experiences working in his father's Berlin shop as a young lad. At the film's January 25, 1940 premiere at Radio City Music Hall, Lubitsch remarked, "I have known just such a little shop in Budapest...The feeling between the boss and those who work for him is pretty much the same the world over, it seems to me. Everyone is afraid of losing his job and everyone knows how little human worries can affect his job. If the boss has a touch of dyspepsia, better be careful not to step on his toes; when things have gone well with him, the whole staff reflects his good humor.
According to Bright Lights Film Journal website, When Kralik mentions "You read Zola's Madame Bovary," Klara immediately corrects him: "Madame Bovary is not by Zola," she snipes. The joke here is that though Klara knows who wrote Madame Bovary, she doesn't understand that she herself is living exclusively in Emma Bovary's world of impossible ideals.
