The Angel that Stands by Me (1983) by Allie Light and Irving Saraf, documents North Carolina visionary artist Minnie Evans near the end of her long life. The film, 29 minutes long, is available to watch at Folkstreams.net, along with a transcript and other information. The film beautifully connects Evans's art with her family, with her work as a gatekeeper (from 1949 to 1974) at Wilmington's Airlie Gardens, and with her spiritual life.
