A film about disability rights activist Judith Heumann is set to open the Toronto International Film Festival. The movie, titled "Being Heumann," will have its world premiere on the festival's opening night.

The festival will run from September 10 to September 20. Heumann was a prominent figure in the disability rights movement, and her advocacy played a role in the creation of the Americans with Disabilities Act.

Further details about the film and the festival are available from the source. The film's director, Siân Heder, has previously worked on other notable projects, including the Academy Award-winning film "CODA".
