Sian Heder’s activist drama “Being Heumann” is set to open the 51st Toronto International Film Festival in 2026. The film, directed by Heder (who previously made the Oscar-winning “CODA”), stars Ruth Madeley as disability rights advocate Judith Heumann. “Being Heumann” premieres at TIFF on September 10 at Roy Thomson Hall, according to the festival announcement. Multiple outlets identify Heumann as a leading figure in disability rights, including her role as an advocate linked to the Americans with Disabilities Act. The story centers on Heumann’s life and activism. Heder’s previous film “CODA” became a major festival success after launching at Sundance, and it also went on to win major honors. The reporting also notes Apple’s involvement in releasing Heder’s films, including “CODA,” alongside “Being Heumann.”
