That's the way a friend once described it to me when he saw an ad for it at a former local art house. (I miss the Roxy.) Was he ever right.
If you only know Frank Capra from the perennial Christmas chestnut It's a Wonderful Life (1946), you should try to find this movie. It is a much darker movie. It deals with the sexual attraction that grows between a white missionary's wife for a Chinese warlord. When she becomes seperated from from her husband during a battle that overwhelms an orphanage, Barbara Stanwick finds herself held captive by an sophisticated general.
The desire between the two blind them to the dangers that surround them.
