We saw the 73-minute shorter re-cut USA version "Restless Heart" and highly recommend it as a very good introduction to the thought and times of one of the greatest theologians of the Christian era. The screenplay does a masterful job of presenting not only the Christian, but also the social, political, and psychological problems of the time -- which, it turns out, were not significantly different from our own.
Technically, the dubbing could have been better, especially early on, but the story itself absorbs you, and you soon don't notice. Well acted, fairly well staged, and definitely worth trying to find in its limited (so far) release in the US.
