No screenplay credit on "Love Letters", but a good story and film structure propels this effective treatment on a familiar subject.
It's usually a female character in a story like this, but for once we get Dillon Day as a novelist holed up in his new atmospheric home, that may or may not be haunted. In any event, he gets inspiration to work on his book, with due date looming soon and emphasized by his task-master of an agent, played by director Lee himself. That inspiration comes from a series of love letters written on red stationery, that keep arriving at his mail box addressed to the former owner of the place.
The Finnish beauty Karina is fabulous to look at, as usual, as the letter-writer, whose identity we learn about in the explanatory final reel. Before then she does plenty of humping, both in her own ample form and appearing as other women, with Dillon of course getting his share of the largesse. The sex scenes are presented as erotic dreams, with a very lengthy femme cast delivering the goods for director Lee.
