(b. 1965, Volgograd) is an artist-actionist and filmmaker. In 1995 Mavromatti founded Independent Film Union SUPERNOVA supposed to be a fortress of Moscow radical cinema. Several films produced by movement participants like «The Green Elephant» (1999) and «Bastards» (2000) became cult movies and inspired many VK fan-communities to emerge. In 2014 together with Boryana Rossa they established new trajectory in their filmmaking, entitled post-cinema. It incorporates social and moving image production phenomenas that appeared as a result of online social networking and video blogging. The first film in this direction has been «No Place for Fools», which is entirely made of YouTube videos. It won the award for best documentary in the Russian Film Festival Dvizhenie, Omsk, 2015. Lives and works in New York, USA and Bulgaria.
