Accustomed to the stage since the 1970s, Niels Arestrup has always made his career oscillate between theatre and cinema. In the dark rooms, he distinguished himself in front of the cameras of Alain Resnais, Claude Lelouch, Roger Hanin, István Szabó (Hungary), Sergio Gobbi (Italy), Guillaume Nicloux, Jacques Audiard, Bertrand Tavernier, Frédéric Schoendoerffer and Albert Dupontel. These prestigious collaborations will earn him six nominations at Les César and 3 awards for best actor in a supporting role: in 2006 (De Battre mon cœur s’est arrêté), in 2010 (Un prophète) and in 2014 (Quai d'Orsay) He was also nominated in 2011 for L’homme qui voulait vivre sa vie, in 2016 for Diplomatie, and in 2018 for Au revoir là-haut. He also exported himself across the ocean to shoot movies with Steven Spielberg, Angelina Jolie or Julian Schnabel.
In 2015, on the occasion of Volker Schlöndorff’s presentation of Diplomatie, Niels Arestrup – then guest of honour – gave a master class at Les Arcs Film Festival for its 7th edition.
