This 1940 movie is the first part of a rather odd TCM double feature. This Ernst Lubitsch film, starring Margaret Sullavan and James Stewart, is about rival shop owners who fall in love with each other, unknowingly, through anonymous correspondence. The second part of the double bill, at 10 p.m. ET, is 1949’s In the Good Old Summertime, a musical remake of the same story, starring Judy Garland and Van Johnson. And both of these movies are direct precursors to another successful remake, 1998’s You’ve Got Mail, starring Meg Ryan and Tom Hanks.
