What is the Being Heumann movie about?

Judy Heumann's disability-rights activism.

Being Heumann is Siân Heder's dramatisation of disability-rights pioneer Judy Heumann, played by Ruth Madeley, with Mark Ruffalo also starring; it centres on the 1977 sit-in protest Heumann led, a 28-day action that helped launch the American disability-rights movement [4, 5]. The film, cast partly with actors with disabilities, opened the 51st Toronto International Film Festival on 10 September, marking Heder's first feature since CODA [1, 2, 5]. At the premiere Heder said "collective action matters," framing the story against present-day concerns about groups being left behind [3].
