SERIES TRADEMARK: In all three parts of the trilogy, an elderly person can be seen trying to throw an empty bottle into a recycling bin. In this final entry, Valentine (Irène Jacob) helps her, while in the other two parts the main character just watches.
Citing that it does not meet enough of the necessary guidelines concerning a film's "artistic control" within a foreign co-production, the Academy of Motion Picture Arts and Sciences disqualified the film from competing as Switzerland's official entry for the Academy Award for Best Foreign Language Film. (In an unprecedented move, Switzerland rejected the Academy's offer to submit another film.) Miramax Films' co-chairman Harvey Weinstein persuaded more than sixty industry heavyweights to sign a letter of complaint urging the Academy to reconsider its stance, to no avail.
Prior to filming, Kieslowski asked Irène Jacob if she ever wished for a different name when she was a child. Jacob told him that she had always wanted to be named Valentine, and the name was used for her character.
