The Passion of Joan of Arc by Carl Dreyer (1928)

This movie by Dreyer is a work of art.  It's one of the best directed films ever.

In the film there's an interesting contrast between Joan, for whom the Christian religion has become real, and the bored, apathetic and cynical English clergy, for whom Christianity became a job.

Dreyer never chose a definitive soundtrack, so this version of the film has a contemporary soundtrack by a group of musicians from Chicago who call their band: Joan of Arc.  I kind of like their soundtrack.
