Jean Cocteau's play La Voix Humaine (The Human Voice) opened at the Comédie Française in 1930 as a atar vehicle for Belgian actress Berthe Bovy, then popular in Parisian stages. The work involves a woman, only identified as Elle = She, speaking on the telephone with his lover of several years, who is leaving her.for another woman. Her interlocutor is silent for the duration and we don't even know for sure if he is listening or if the connection has been broken.
The play had an enduring popularity, and has been since in the repertory of many theater companies. It was put on screen several times, among them by Roberto Rossellini (first episode of L'Amore 1946: actress Anna Magnani) and by Ted Kotcheff (1966: actress Ingrid Bergman). It even had a second life as an opera by Francis Poulenc in 1958, which has been as well accepted as the play and is still being staged and recorded.
This being the Almodóvar version, we may expect some off the wall happenings. One is a very funny scene where the protagonist browses for axes in a hardware store that seems to have an unusually large inventory of the item. On another, the axe in question is used in a hilarious way. We are shown mid-movie that She's apartment is actually a set in a sound stage which is perhaps a gentle dig at he artificiality of the play. And, last but not least, we have the director's trademark, cinematography in gloriously saturated colors. Tilda Swinton does an outstanding job as She; she tones down the melodrama and borders on the humorous at times. All in all, a refreshing take on the play and the best version I have seen.
