I have seen The Amazing Colossal Man several times and is one of Mr BIG's better movies.
As a plane crashes just before an atomic test at Camp Desert Rock, Glenn Manning goes to see if there are any survivors despite the danger. The bomb goes off and he gets caught right in the middle of the blast. He suffers 90% burns but doctors are very baffled when they take his bandages off to find him without any scars at all. Gradually, he increases in size and eventually, he goes on the rampage through Las Vagas and kills Major Lindstrom when he injects him with a formula to reduce him in size with the needle. Manning is shot by the Military and falls into the Colorado River but is not dead...
One of the better parts of the movie is where Manning kills the Major with the needle he was going to inject him with.
The cast includes Glenn Langan as Manning and 50's sci-fi regulars Cathy Downs (The She Creature), Russ Bender (It Conquered the World) and James Seay (Killers From Space). Most of the cast are used to fighting giant creatures looking at other sci-fi movies they were in at this time.
Despite the low budget, this movie was fun to watch.
Rating: 3 stars out of 5.
