The Sandman: One of several collaborative dance films by the Brothers Quay & (dancer, choreographer) William Tuckett. Little enough info around on line, but there's briefly by way of Wikipedia entry. Adapted rather loosely from the works of the E.T.A. Hoffman. Familiar Quays' tropes, much in evidence: automata, trompe l'oeil effects, etc. No credit on the sound design (which is fairly elaborate), tho' that is possibly Larry Sider.
