1940 movie directed by Ernst Lubitsch
and starring Jimmy Stewart
and Margaret Sullavan
Holiday movie set in a Budapest shop. Two sales clerks fall in love with each other, though they do not know it because they meet through a series of letters. Well written and well acted, it is among my favorite movies.
In the Good Old Summer Time in 1949 starring Judy Garland and Van Johnson
You've Got Mail in 1989 starring Tom Hanks and Meg Ryan
