"Nick of Time" is a great example of what can be done with the economy of the 30 min anthology episode. A very well-directed episode, the story is perfectly paced to create a mounting sense of strangeness and fear. What's so interesting to consider is that nothing happens in this episode that could not occur in real life. There is nothing supernatural of unexplained. The husband (extremely well-played by William Shatner) discovers how deeply superstitious and fatalistic he really is when he encounters an apparently harmless fortune-telling machine in an Ohio greasy spoon. His level-headed wife (Patricia Breslin) contributes to the drama by first humorously encouraging him, then becoming disturbed and fearful when she sees her husband falling under the spell of his own imagination.
It's a perfect case of a brilliantly realized story in short format. An hour-long show on this theme would need padding and most likely fall flat.
