Krzysztof Kieślowski in the context of "Trilogy"

The Three Colours trilogy (French: Trois couleurs, Polish: Trzy kolory) is the collective title of three psychological drama films directed by Krzysztof Kieślowski, co-written by Kieślowski and Krzysztof Piesiewicz (with story consultants Agnieszka Holland and Sławomir Idziak), produced by Marin Karmitz and composed by Zbigniew Preisner. The trilogy consists of Three Colours: Blue (1993), Three Colours: White (1994), and Three Colours: Red (1994). The trilogy, while not sharing a specific storyline, thematically examines the French Revolutionary ideals, and is interconnected, particularly in Red, with cameo appearances of characters from Blue and White.

Represented by the Flag of France, the trilogy is an international co-production between France, Poland, and Switzerland in the French language, with the exception of White in Polish and French. All three films garnered widespread acclaim from reviews, with Red receiving nominations for Best Director, Best Original Screenplay, and Best Cinematography at the 67th Academy Awards.

Dekalog (pronounced [dɛˈkalɔk], also known as Dekalog: The Ten Commandments and The Decalogue) is a 1989 Polish drama television miniseries 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 decalogue of the Ten Commandments. Each installment explores characters facing one or several moral or ethical dilemmas as they reside in an austere housing project in 1980s Poland.

Exhibited in its entirety at the 46th Venice International Film Festival, the series, Kieślowski's most acclaimed work, was said in 2002 to be "the best dramatic work ever done specifically for television" and has won numerous international awards, though it did not receive wide release outside Europe until the late 1990s. It is one of fifteen films listed in the category "Values" on the Vatican film list. In 1991, filmmaker Stanley Kubrick wrote an admiring foreword to the published screenplay, wherein he stated that Dekalog was the only film masterpiece he could think of.

The Double Life of Veronique (French: La double vie de Véronique, Polish: Podwójne życie Weroniki) is a 1991 drama film directed by Krzysztof Kieślowski, and starring Irène Jacob and Philippe Volter. Written by Kieślowski and Krzysztof Piesiewicz, the film explores the themes of identity, love, and human intuition through the characters of Weronika, a Polish choir soprano, and her double, Véronique, a French music teacher. Despite not knowing each other, the two women share a mysterious and emotional bond that transcends language and geography.

The Double Life of Veronique was Kieślowski's first film produced partly outside his native Poland. It won the Prize of the Ecumenical Jury and the FIPRESCI Prize at the 1991 Cannes Film Festival, as well as the Best Actress award for Jacob. Although selected as the Polish entry for the Best Foreign Language Film at the 64th Academy Awards, it was not accepted as a nominee.
