Cary Joji Fukunaga spoke about his incredible debut feature, “Sin Nombre” at length in the post-screening Q&A at the SXSW Film Festival, but we thought our friends at Lakeshore records would get a kick out of the fact, we publically reminded him who was putting out his own soundtrack (which came out digitally yesterday and comes out on disc on march 24). He also discusses where he found the actors in the film, the excellent leads Edgar Flores and Paulina Gaitan, the former being a non-actor the latter an up-and-coming actress from Mexico, who is quite remarkable in the film.
