Tell bickering Budapest gift-shop workers Alfred and Klara that they love each other and they might call you crazy. No lovers can compare to the romantic, secret pen pals each knows only as Dear Friend. What Alfred and Klara don't know, or course, is that they are each other's Dear Friend. In the third of their four luminous screen pairings, Margaret Sullivan and James Stewart star in this valentine to love wrapped in the ribbon of director Ernst Lubitsch's trademark touch: wit instead of buffoonery, sentiment instead of sentimentality, affection instead of attitude. As enchanting as it was yesterday, The Shop Around the Corner was breezily updated to the electronic age when Tom Hanks and Meg Ryan clicked together in You've Got Mail. In any age, your patronage will be cheerfully rewarded.
