"The Loss of Nameless Things" about Nevada City writer Oakley (Tad) Hall III, which premiered two months ago at the notable Cinequest San Jose Film Festival, will show one time only Sunday in Nevada City.

The film was directed and produced by Bill Rose, an award-winning documentary maker, who will answer questions after Sunday's screening.

Part of the 103-minute documentary was shot locally in March and April of 2002 when Hall's play, "Grinder's Stand (A Tragedy of Blood)," was presented at the Nevada Theatre.

"The Loss of Nameless Things" is about Hall's literal fall from grace and his nonstop efforts to rebuild his artistic life. Film footage includes Hall's work almost two decades later with Foothill Theatre Company, which presented "Grinder's Stand," the play Hall was revising the night he mysteriously fell from a Lexington, N.Y., bridge and suffered severely debilitating brain injuries in 1979.

Hall's emerging theatrical career as a founder, artistic director and playwright for Lexington Conservatory Theatre unexpectedly halted that night 25 years ago in Lexington. Hall, who would later be admitted to three hospitals for multiple reconstructive surgeries, suffered immense memory loss.

Yet Hall refused to give up his artistic dreams, as shown in "The Loss of Nameless Things." After moving around the country for 15 years, Hall moved to Nevada City; his sisters Brett Hall-Jones and Sands Hall lived here, and his parents lived in Squaw Valley and San Francisco.

To this day, the eight-year Nevada City resident can't remember how he fell off the bridge.

Hall also doesn't understand how he was rehabilitated, other than through constantly reading and writing. Hall was able, however, to finish his verse play, "Grinder's Stand (A Tragedy of Blood)," which questioned the popular opinion that American frontiersman-explorer Meriwether Lewis killed himself.

Sunday's screening is 7:30 p.m. at the Nevada Theatre, 401 Broad St. Admission is $5.50 general and $4.50 for children 12 and under and seniors.
