I liked this film. I liked it a lot. Sure it is by no means anything other than a poorly-crafted, deficient special effects laden film about a man that survives a plutonium blast that starts to grow almost 8 inches a day. Soon Colonel Glenn Manning becomes fifty feet high and starts to lose his mind. Bert I. Gordon is able to do something he rarely ever does, and that is make you care a bit for the characters. Glen Manning is punished for a good deed and his heroic personality, and the irony of his situation is never lost on him or the audience. Glenn Langlan does a pretty good job as the giant man despite the acting experience it was trying to seem gigantic. The rest of the cast is not quite at his mediocre level. Cathy Downs does a credible job as his love interest, but the two fellas playing the doctors had all the bedside charm of a brick wall. How bout that scene with the camel and the elephant? What a hoot! The special effects are some of the cheapest to come out of the fifties. Giant Glenn Manning is just projected onto other film. Nothing too special about that. Except in the close-ups, the giant always looks transparent(a symptom of the projection process...watch Attack of the 50 Foot Woman and you will see the same effect). The scene with the giant hypodermic needle is easily the best. Glenn finally gets his point across to an army scientist. The biggest low of the film for me was the ending. It seems very abrupt, almost like, "Hey, we ran out of money....let's end it like this....real fast!" Shortcomings notwithstanding...give The Amazing Colossal Man a try if you like good/bad science fiction films from the fifties. If your ideas of horror classics are Friday the 13th and Nightmare on Elm Street...stay away...nothing in this film will entertain you.
