The Amazing Colossal Man (1957)
Manning: What kind of sin could a man commit in a single lifetime to bring this upon himself?
[Dr. Lindstrom explains to Carol that Glenn's heart isn't growing as fast as the rest of his body]
Dr. Paul Linstrom: Now, the reason for this is rather technical, Carol, but to give you a simplified layman's explanation, it might be explained that, since the heart is made up of a *single* cell for all practical purposes, instead of millions of cells like the rest of the organs of the body, it's reacting in an entirely different manner to this unknown stimulus or forces behind this whole thing.
Manning: [reading newspaper] "Man Lives Through Plutonium Blast"
Manning: They call THIS living?
Manning: Perhaps it isn't I who's growing, but it's everyone who's shrinking!
Henry: [tosses bottle after seeing the Colossal Man] Not another drop! Not another drop as long as I live!
Manning: I just don't want to grow anymore. I don't want to grow anymore!
