Burt I. Gordon's "The Amazing Colossal Man" was the first sci-fi film I saw as a kid that actually scared me. But it wasn't the effect of a bald Col. Glenn Manning running around Las Vegas that I found frightening; it was the actual atomic bomb test-blast footage I found so horrific. At the age of six, seeing houses blown like matchsticks into blazing debris was enough to cause nightmares. The same footage (recently restored by Peter Kuran for the "explosive" documentary "Trinity and Beyond: The Atomic Bomb Movie") can still sends shivers down the spine of any self-respecting anti-nuker.
"The Amazing Colossal Man" still ranks as one of the better b-grade drive-in movies. It is unintentionally funny, full of impossible science and very entertaining. The cast does their best with the material (from a script by George Worthing Yates) but I suspect no one took the project very seriously, least of all Mr. Gordon. It is also highlighted by another thunderous Albert Glasser score.
