Born in Greece, Marmatakis had wanted to live in London since he was a teenager and ended up studying graphic design at Camberwell College of Arts and the Royal College of Art in the 1990s. While working in an Athens advertising agency he met Lanthimos, who was then a successful freelance director of ads and music videos, and also Efthymis Filippou who would go on to write almost all of Lanthimos’s films. In 2003 Marmatakis co-founded the Athens design studio MNP with Katerina Papanagiotou (their logo appears on the Dogtooth poster above) and since 2009 he has worked as a freelance designer as well as a visiting professor at the Vakalo College of Art & Design in Athens. Marmatakis has designed the promotional posters for all of Lanthimos’s movies. He's the graphic designer of all Lanthimos’s movies except his first film.
