The Keys of the Kingdom is a 1940s-era movie about a missionary priest in China in the early 1900s, with Cary Grant in the leading role. Boy, he was a tall drink of water, wasn't he?
It was interesting, if dated. The Chinese were portrayed pretty stereotypically, but I guess that's to be expected, given the era. I liked the book better, mainly because they cut so much out in the movie, including the part where the priest and two of his companions get waterboarded in the river - that was the most vivid and compelling part of the book for me.
Oh, and I was surprised to see Vincent Price show up in the role of a bishop - How many movies was that guy in, anyway?
So! An okay movie. I probably wouldn't pay to rent it again, but if it turned up on TCM on a rainy Saturday afternoon, I'd watch it.
