Directors that inspire me are Ingmar Bergman, Stanley Kubrick, David Fincher, Larry Clark, Michael Haneke, Ulrich Seidl, Gaspar Noe, Martin Scorsese among others.
Drama and Thriller mainly. At least when it comes to writing stories. I can also enjoy action movies, comedies, sci-fi movies, ... as long as they are well crafted and have thought value or don't take themselves too seriously. From time to time I also need my dosage of classics or art house movies.
