Sundance Institute Short Film Challenge 2015 Five of these films were selected among 1,387 submissions from 89 countries on, a creative platform which powered a global call for film entries that used the transformative power of storytelling to generate discussion, shift perceptions around extreme worldwide concerns and harness the power of independent film to create a global conversation about these issues. Contributors on Tongal could submit finished films or story ideas based on the above topics. This program is supported by the Bill & Melinda Gates Foundation, which encourages people inspired by these stories to join, a global movement that works towards ending extreme poverty in the world by 2030.
