Encounter in the Third Dimension on AllMovie

The first large-format 3-D film to open simultaneously in all three IMAX theatres in Los Angeles, Encounters In The Third Dimension uses a visit to an eccentric inventor who has invented a new 3-D device, "Real-O-Vision," as a framework for a series of spectacular three-dimensional sequences, capturing both real life events and bizarre computer-animated fantasy worlds. The film also traces a brief history of 3-D in the movies, and features a guest appearance from Elvira, Mistress of the Dark (aka Cassandra Peterson).
