While not a direct sequel to Invisible Man Appears, Invisible Man Vs the Human Fly and the latter are usually thought of as companion pieces. Human Fly is more preposterous and more imaginative, and therefore more entertaining, then Invisible Man Appears. Both films are interesting in their serious approach to the police procedural genre element, and because Fly is more effective with this aspect of its story, on that level it is also better than the first film. It is not a great movie, but both films are odd curiosities within Japanese post-war cinema culture, and are worth viewing for fans of the period and certainly for fans of 1950s world sci-fi cinema.
