movie recommendation for thief fans!

There is a french movie by robert bresson called -A Man Escaped- or in french:-Un condamné à mort s'est échappé ou Le vent souffle où il veut-

It is pretty much the blueprint for the game concepts of real stealth games like the thief series or tenchu. It's all in there. Stealth, sneaking, careful observation, guards , avoiding noise, careful planning
It's also a skillful masterpiece of minimalistic realism cinema
check it out!
He also made a great movie thats called The Pickpocket(aha!). Although the title suggests more resemblance of the thief games, a man escaped is what you should definitely watch.
Watch them both!
