The Incredible Shrinking Man. 1957.
One film that always seems to entertain little old me with every viewing, despite the low budget, the film's special effects are terrific and the second half of the story basically resolves itself into a struggle for survival for our unfortunate hero as he has to battle various elements, the family cat, a spider, water, the re-dimension of objects around him, his own weakness due to hunger which a normal person would more or less take for granted.
