Chicago Reader review:
Robert Bresson made this short electrifying study in 1959; it's one of his greatest and purest films, full of hushed transgression and sudden grace. A petty thief (Martin Lasalle) becomes addicted to the art and thrill of picking pockets. He loses his friends and fiancee, and begins to live like a monk, concentrating his entire being on his obsessional, increasingly devotional acts of theft. If the film seems familiar, that's because Paul Schrader recycled great chunks of it in his scripts for Taxi Driver, American Gigolo, and Raging Bull. But the original retains its awesome, austere power. With Pierre Leymarie and Marika Green. In French with subtitles.
Here (and above) is the trailer.
