For the Paris Opera's 3e Scène, actor, director and writer Alexandre Steiger has imagined a perambulation between comedy and poetry in the basement of the Palais Garnier. Paul and Adele, extras in the opera Tristan and Isolde, take advantage of a coffee break to go in search of the legendary underground lake. Their roamings from the trivial to the sublime draw the lines of a modern-day Map of Tendre and invite us to dream. De longs discours dans vos cheveux makes exquisite use of dialogue for, as the director points out in this interview, it is words that weave the affairs of the heart. In the company of his accomplices, actors Judith Chemla and Samuel Achache, Alexandre Steiger discusses the creation of the film and their experience of the 3e Scène.
