The tale had all the hallmarks of a baroque Paul Bowles short story, set among the remaindered possessions of Bowles himself: a film director gets a call from a stranger, who says he has stumbled across an original print of the filmmaker’s long-lost first film in a windowless Tangier apartment, coated in dust and insect powder. The director, Sara Driver, at first thought the call might be a joke, but for reasons almost as strange as fiction, she kept listening.

In the late 1970s she had fallen in love with a haunting 1948 Bowles story called “You Are Not I,” about a young woman who escapes from an asylum, and decided she wanted to make a film of it. With no money for the rights and the thinnest of shoestrings to make the movie itself — a $12,000 budget, some of it supplied by her small salary at a copy shop — she forged ahead anyway. And before its well-received premiere at the Public Theater in 1983, she shipped a print of the 48-minute black-and-white film, the first screen adaptation of one of Bowles’s stories, to his apartment in Tangier, Morocco, praying simply not to be sued.

“To my great relief, he liked it,” Ms. Driver recalled recently. “And not only that, but he wrote me back with a long, detailed critique of the film, saying, among other things, that he thought one woman overacted — which he was right about.”
