Stereo (full title Stereo (Tile 3B of a CAEE Educational Mosaic)) is a 1969 Canadian science fiction film directed, written, produced, shot and edited by David Cronenberg in his feature film debut. Starring Ronald Mlodzik, who would go on to appear in later Cronenberg films Crimes of the Future, Shivers, and Rabid, the film was Cronenberg's first feature-length effort, following his two short films, Transfer (1966) and From the Drain (1967). The plot follows several young volunteers who participate in a parapsychological experiment.
