War of the Colossal Beast (aka Revenge of the Colossal Man and The Colossal Beast) is a 1958 black-and-white science fiction film directed by Bert I. Gordon, produced by Carmel Productions, and distributed by American International Pictures. The film was released theatrically in 1958 on a double bill with Attack of the Puppet People.

It continued the storyline of the 1957 movie The Amazing Colossal Man, although it was not marketed as a direct sequel and featured a different cast. Both The Amazing Colossal Man and War of the Colossal Beast were later mocked on the television series Mystery Science Theater 3000.

Upon hearing of several recent robberies of food delivery trucks in Mexico, Joyce Manning (Sally Fraser), Army officer Lt. Col. Glenn Manning's sister, becomes convinced that her brother (Dean Parkin) survived his fall from the Boulder Dam (as seen in The Amazing Colossal Man). Along with Army officer Major Mark Baird (Roger Pace) and scientist Dr. Carmichael (Russ Bender), she goes to Mexico to look for her brother.

Manning had, in fact, survived his fall, but was left disfigured and nearly mindless. Manning is captured, drugged by the Army, taken back to the United States, but again escapes and goes on a rampage through Los Angeles and Hollywood. Eventually, Joyce makes him come to his senses. Realizing what he has done, Manning kills himself by electrocution on high-voltage power lines near the Griffith Observatory.

War of the Colossal Beast was produced, directed and written by Bert I. Gordon and co-produced with Samuel Z. Arkoff. Although most of it is shot in black-and-white, the ending was shot in color for the electrocution scene and doctored black-and-white. The producers decided to use the very heavy make-up on Dean Parkin as a way to disguise the fact that a different actor was playing Col. Manning, especially since a dream sequence flashing back to the original film featured Glenn Langan, the star of the earlier film.
