The Big Muddy Film Festival is one of the nation's longest-running student-organized film festivals, originating from Southern Illinois University (SIU) Carbondale. Held annually in Carbondale, Illinois, the festival showcases works from independent filmmakers and students, featuring films across various genres including narrative, documentary, animation, and experimental. Known for its focus on social justice, community, accessibility, and environmental themes, the festival often highlights strong documentaries and presents awards in multiple categories, including special recognitions for SIU alumni and films addressing environmental issues. The event is typically free and open to the public, offering both in-person screenings and, at times, online accessibility.
