In 2011 Davenport directed the feature documentary
Too Sane for This World. This film explores the challenges, gifts and unique perspectives of 12 adults on the autism spectrum. The film features an introduction by
Dr. Temple Grandin. Many adults on the autism spectrum discover their condition much later in life, some being diagnosed as late as the age of forty. Knowing that you are on the spectrum can bring a great relief and understanding of oneself, but also a label that brings its own set of discrimination. In getting these important points across, the film benefits from a remarkably articulate set of interviewees, several of them high achievers by anyone's standards. Simply by being there, they should go some way toward easing the fears of parents with kids on the spectrum. There are also interviewees who describe themselves as 'slow', however, and talk about the difficulties they had at school. Assured and assertive as they are (partly thanks to interview questions designed by other people with autism), they're a reassuring example for people with all kinds of different problems in childhood, and their inclusion highlights how rarely we hear any such voices. Between them, these diverse people do an effective job of putting across where the differences are that make fitting into mainstream society so difficult. Their different backgrounds keep their stories interesting and they quickly do away with the notion that autistic people have no sense of humor. This contributes to the film's other achievement – illustrating how much common ground there is and showing that mutual understanding, whilst it may pose challenges, is far from impossible. In 2013, Davenport directed the feature documentary
Citizen Autistic. The history of civil rights in America has been marked by the hard-won progress of one category after another of oppressed and marginalized citizens who stand up and demand recognition, respect, and equal access to the benefits of modern society. William Davenport's film Citizen Autistic brings us an inside look at the front lines of the autistic civil rights movement, showcasing activists who experience autism and self-advocates on the front lines of this struggle for inclusion, and freedom from persecution. Featuring notable figures such as
Ari Ne'eman, co-founder and former president of the
Autistic Self Advocacy Network, and Landon Bryce, of thAutcast.com, this documentary details what the emerging neurodiversity movement is up against, from the torturous electroshock "treatment" that takes place at the
Judge Rotenberg Center in Massachusetts, to the dehumanizing and alarmist marketing campaigns of fundraising juggernaut Autism Speaks. Promoting a philosophy of neurological variation as simply another aspect of human diversity, these tireless activists embody the call of the disability rights movement: "Nothing About Us, Without Us." In 2014 Davenport released the short documentary
Conquering Heights. In 2013, Davenport directed a music video for the band Array, which features Robyn Steward and Mark Tinley, who are both on the autism spectrum. The video is for the song, "Spacecadet" was released on April 2, 2013 - World Autism Day. Davenport has been completed a series of films that focus on the music and zine scenes that originated in the 1980s. In 2015 Davenport completed a series of documentary films that explore the world of experimental and noise music titled
Unsound Redux. The series consists of four films: "Great American Cassette Masters", "The New Punks", "Ziners", and "The People's Music". Continuing his interest in experimental music Davenport completed two documentaries in 2018: "Media About Media about Media: The Negativland Story" and "Hunting Lodge: The Story of Two Nomad Souls". ==Autism activist==
