SLIFF is a regional, internationally themed film event dedicated to exploring cross-cultural understanding through the art of the cinema. The organization's mission is to showcase the best in international, documentary, and American independent cinema. Believing that we discover something about ourselves when we learn about others’ cultures and perspectives, SLIFF offers programs that provide glimpses of the human experience from around the world and thoughtfully address issues of race, ethnicity, and sexual identity. The festival is especially concerned with providing local filmgoers the opportunity to see works that would otherwise never screen in St. Louis.
USA Today named SLIFF one of the 2019 top "10 amazing film festivals worth traveling for."
