Joe Swanberg is an American independent filmmaker, often associated and credited with helping pioneer the "mumblecore" film movement. He's made a career of producing/ directing/ writing micro-budgeted films, often acting in his own features as well as enlisting his friends to help out. Much of the dialogue in his films is improvised, although he recently has begun to redefine himself by challenging the very parameters of what would typically define the "mumblecore" style.
Many of Joe Swanberg's films have done the indie film festival circuit, and even been prominently featured by IFC and the Sundance Channel.
