If you enjoyed “You’ve Got Mail” you have this film to thank. Co-workers James Stewart and Margaret Sullavan barely acknowledge each other during the work day but are unknowingly in the midst of a love affair going on via the letters they write to each other. Because it’s the 1940s, the humor and the romance are both a bit corny but the chemistry between Stewart and Sullavan is such that you don’t care how corny it is. The stars eventually made four films together, but this one is the one you’ll remember most. Sweet, a little silly and very romantic. Meg Ryan and Tom Hanks are nice but they can’t touch these two when it comes to an oblivious love affair.
