Sam Forstman is an old man who lives with his granddaughter Marnie Kirk and her husband Doug. Sam lives a simple life and doesn't sleep much anymore. He's usually up at all hours tinkering on his grandfather clock, something that worries Marnie as his attention to the timepiece verges on the obsessive. The reason for that however is quite simple: he is convinced that should the clock ever stop, he will die. Written by garykmcd

Did You Know?


William Froug had Richard De Roy rewrite the George Clayton Johnson teleplay "Tick of Time" before it was aired as The Twilight Zone: Ninety Years Without Slumbering (1963). Johnson was displeased with this and ultimately never reconciled with Froug, and never contributed to The Twilight Zone (1959) again. See more »


We see the spirit leave Forstmann's body while he is asleep and walk to the foot of his bed. The spirit is a "see-through" image of him but the real body has "see-through" feet under the covers when seen in the side view. See more »


Narrator: [Closing Narration] Clocks are made by men, God creates time. No man can prolong his allotted hours, he can only live them to the fullest - in this world or in the Twilight Zone.

Pretty thin...but at least the ending did catch me by surprise
23 June 2010 | by (Bradenton, Florida) – See all my reviews

While this is not true of most episodes of "The Twilight Zone", this one could easily be summarized in a single sentence--mostly because it has such an incredibly thin plot. An old man (Ed Wynn) believes that when his favorite grandfather clock fails to be wound, he will die--and his family assume he's crazy. To put it bluntly, there just isn't enough to this particular show to justify 25 minutes of your life. The plot is very thin. About the only things going for this particular show are Ed Wynn's performance and the nice twist ending--and ending, however, that seemed VERY unlike the rest of the series in spirit and style. As usual, Wynn's performance is sweet and well worth seeing, as he was a heck of an entertainer. Otherwise though, there just isn't a lot to this show and it's an easy one to skip.
