Sometime in the mid-seventies I saw a film on TV about a couple that were somehow stuck in a moment of frozen time (i.e. they walked around normal while the world around them was stopped in mid-stride). I didn’t see the film’s beginning or ever see it again so I don’t know how or what caused their situation. They soon discover that they aren’t exactly ‘frozen’ in time, but in fact time is very slowly progressing around them, like the hands on a clock.
The core of the film was that the couple discovered that there is a large truck who’s emergency brake has failed and is about to roll over their young daughter on her tricycle, who’s in the middle of pedaling behind the truck. I seem to recall that the father somehow rigs up a seat belt around the truck’s steering wheel and the truck’s E-brake so it will engage when it moves. Also I think maybe to due this the father winds up getting ‘stuck’ there after insisting that his wife go back to where they started and escape, but I’m not sure.
I know it sounds like one but it was not a Twilight Zone episode, though it had the look & feel of one (which is was why I watched it). It was in B&W and was probably early 60s. It had no stars that I remember. I remember it being of film length but it could have perhaps been one of the hour-long TZ clones (Outer Limits etc.)
