All three installments were co-written by Kieślowski and Krzysztof Piesiewicz (with story consultants Agnieszka Holland and Sławomir Idziak), produced by Marin Karmitz and composed by Zbigniew Preisner.

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.

In the case of Blue, it is the lamp of blue beads, and a symbol seen throughout the film in the TV of people falling (doing either sky diving or bungee jumping); the director is careful to show falls with no cords at the beginning of the film, but as the story develops the image of cords becomes more and more apparent as a symbol of a link to the past.

In the case of Red, the judge never closes or locks his doors and his fountain pen, which stops working at a crucial point in the story.

In Blue, while Julie is searching for her husband's mistress in the central courthouse, she accidentally steps into an active court trial and is immediately turned around by security.

Music for all three parts of the trilogy was composed by Zbigniew Preisner and performed by Silesian Philharmonic choir along with Sinfonia Varsovia.
