The Shop Around the Corner has moment after moment of this subtle and gentle humanism. It's a movie that gets even better with repeat viewings.
The Shop Around the Corner (1940): A delicate classic with an exceptional ensemble that's at once a drama and a comedy and makes you feel that despite all that can go wrong, all is right with the world.
