Like father, like son. This is a black & white sequel to the color original. The sone of the originals' father starts the same experiments as his father and the same thing happens to him. The acting is pretty good (Price and Halsey do a very good job) but the makeup on Halsey is laughable, the plot has nothing fresh or original to it and it's nowhere near as intelligent as the original. A pretty dull little film. For Vincent Price completists only. Even the sequel after this "Revenge of the Fly" was better!
