Colonel Manning, the amazing 60ft colossal man from the same film, falls into the Colorado River at the end of that film from not-so-friendly military firepower. It seems now though that he survives that only to be swept down river into Mexico where he resides in the mountains and yanks trucks off the road for food. OK, the story in this one in not anything grandiose to be sure, but Bert I. Gordon's follow-up is satisfying to a point. This time around Glenn's sister still believes her brother to be alive and flies down to Mexico - soon to be followed by a military officer who didn't believe her in the first place. Well, Manning is discovered in the mountains, tricked into eating bread loaded with something that knocks him out, and then transported to Los Angelos. From there on we basically get what we got in the first film. There are some differences though. Manning is played this time by the same guy that played the giant with the bad face and eye in Gordon's The Cyclops. He has virtually no dialog. This means that it is a lot more difficult to feel for the character as one might have in the first film. This film does show some attention to the bureaucratic way in which our government works. The acting is competent and Gordon's direction fair. His special effects are again nothing so special. We have the one brief moment of color in the climax. We also get a pretty lengthy flashback taken entirely from the first film. This is a decent sequel but not as "good" as its original source material.
