From NetFlix:

After losing his hearing during the Vietnam War, Richard
Pimentel (Ron Livingston) returns to America, where he falls
in with an unlikely circle of friends and finds a new calling as a
spokesman for the disabled. His efforts as an activist eventually
lead to the creation of the Americans with Disabilities Act. This
inspiring and entertaining true story won the Audience Award
at the 2007 AFI Dallas International Film Festival

It’s not Hollywood but more Hollywood than an Indie. Ron Livingston
comes across as a real person. His relation with his friend with
cerebral palsy is a treat. The language is VERY earthy but is
absolutely appropriate and downright funny. Did you know that
in many cities it was against the law for a disabled person
to appear in public because they were an insult to the eyes
of the other citizens ? I guess I’m a sucker for stories about
real people with their ups and downs. Despite the language, why
shouldn’t kids see it ?
