he Decalogue is a 1989 Polish television drama series directed by Krzysztof Kieślowski and co-written by Kieślowski with Krzysztof Piesiewicz, with music by Zbigniew Preisner. It consists of ten one-hour films, inspired by the Ten Commandments. Each short film explores one or several moral or ethical issues faced by characters living in modern Poland.
The series is Kieślowski's most acclaimed work, has been said to be "the best dramatic work ever done specifically for television" and has won numerous international awards, though it was not widely released outside Europe until the late 1990s. Film-maker Stanley Kubrick wrote an admiring foreword to the published screen-play in 1991.Overview from themoviedb.org
