Emmy Award-winning director Cristina Costantini returns to Sundance in 2025 with her latest feature documentary, Sally, based on the life of Sally Ride. She was previously at the 2018 Sundance Festival with her debut film Science Fair about the competitive world of high school science fairs (co-directed with Darren Foster) and the 2020 Sundance Festival with Mucho Mucho Amor (co-directed with Kareem Tabsch). Science Fair won the Festival Favorite Award at Sundance and was acquired by National Geographic Documentary Films. After it captured the hearts and minds of viewers at festivals across the world, it went on to win an Emmy, spawn a spin-off series, and inspire future generations of scientists. Mucho Mucho Amor was purchased by Netflix in 2020 and went on to garner nominations from the News & Documentary Emmys as well as being honored as Best Documentary of the Year by the Imagen Foundation Awards and the Latino Entertainment Journalist Association Film Awards. Cristina got her start as an award-winning investigative journalist, covering detention centers, immigration, and the opiate epidemic. She has received numerous awards from National Association of Hispanic Journalists for her work as well as a DuPont Award and several Emmy nominations. Born and raised in Wisconsin, Cristina is a graduate of Yale University. She now lives in Los Angeles with her husband Alfie, daughter Penny, and elderly pug dog Harriet. She is a partner at Los Angeles-based production company Muck Media. Nominated for 21 Emmys in 2024, Muck is renowned for its journalistic and character-driven storytelling, spotlighting underdog narratives that resonate with powerful, universal insights.
