War of the Colossal Beast (a.k.a. Revenge of the Colossal Man and The Colossal Beast) is a 1958 black-and-white science fiction film, written, produced, and directed by Bert I. Gordon for his Carmel Productions, and starring Dean Parkin, Sally Fraser, and Roger Pace. It is the sequel to Gordon's earlier The Amazing Colossal Man (1957) and was distributed theatrically by American International Pictures as the top half of a double feature with Attack of the Puppet People. The film's storyline picks up where The Amazing Colossal Man left off, although it was not marketed as a sequel and features a different cast. The film's brief death-scene finale was filmed in color.
