For anyone attending (or trying to attend) any festival or film event, there's an Accessibility Scorecard you can use to report on accessibility (or lack thereof, including if you tried to attend, but got on the website and noticed there were no captioned films).
The data is controlled by FWD-Doc (www.fwd-doc.org, an org of now over 800 disabled filmmakers and allies) and FEAW (feaw.org film event accessibility working group) and is used to help filmmakers in reporting lack of access at festivals (as well as creating data on overall lack of access to festivals, which then is used to apply for grants to fund disabled filmmakers and support accessibility at festivals).
To provide survey response, click on the "complete survey in new window" button mid way down the page. The survey takes about 15-min to complete; version 2.0 will be out in a few months and will be shorter, but for now this version is useful for getting baseline data. The Scorecard Impact Report will be out in a few weeks. https://www.fwd-doc.org/film-event-accessibility...
