The Shop Around the Corner
One of Ernst Lubitsch's most charming and romantic films, this 1940 comic romance finds James Stewart working in a small shop in Budapest and longing for a girl to call his own.
He unwittingly falls in love with his coworker (Margaret Sullavan) as pen pals, but the only problem: they can't stand each other in person. The beguiling nature of the mistaken identity formula that influenced countless films is done to perfection here, and the wry combativeness and delightful banter between the two leads makes this a very special film.
