A documentary about the decades-long fight for disability rights culminating in the passage of the Americans with Disabilities Act is set to premiere.

The film “Change, Not Charity: The Americans with Disabilities Act” follows the twists and turns of a grassroots movement that pushed Congress to mandate curb cuts, ramps and much more to allow people with disabilities access to American life.

Relying on archival footage and interviews with activists, lawmakers and other key players, the one-hour film chronicles how the disability rights movement organized and took to the streets to lobby for the ADA in the face of strong opposition. Things came to a head with the “Capitol Crawl,” when people with disabilities including many wheelchair users dragged themselves up the steps of the U.S. Capitol, leading to the 1990 signing of the ADA.

“I think the message of this film is that civil rights for people with disabilities are just as important as the rights that everyone either has or should have in our society,” said the film’s director, Jim LeBrecht, who has a disability and who is known for his work on “Crip Camp,” an Oscar-nominated documentary about the origins of the disability rights movement.

“There was a coming together of many people, disabled and non-disabled people. Legislators from both sides of the aisle came together in a bipartisan fashion,” he said, referring to the ADA. “I hope that our film will remind our viewers and those in power, that preserving the civil and human rights of people with disabilities benefits everyone.”

Narrated by actor Peter Dinklage, “Change, Not Charity: The Americans with Disabilities Act” will air on PBS March 25 at 9 p.m. ET on “American Experience.”
