Théo Angelopoulos (Θεόδωρος Αγγελόπουλος) is one of the most influential directors, not only in Greece but worldwide.
He dominated Greek film industry from the 1970's and forward but he did it justly, in my opinion.
Some characterise him and his style as belonging to the "Slow cinema" movement but this migt be disputed.
His films are very contemplative and told in a 'floating' and sometimes meditative way but of great visual beauty.
I think I have seen almost all of his films and so has Aurore.
He often casted the Greek actor Christoforos Nezer and most often used only Greek actors in his first films. Later in his career though, he also casted non-greek actors of renown like Marcello Mastroianni, Jeanne Moreau, Harvey Keitel, Maia Morgenstern, Erland Josephson, Bruno Ganz, Isabelle Renauld, Fabrizio Bentivoglio, Willem Dafoe, Irène Jacob, Michel Piccoli, and Christiane Paul.
