Trying to remember the name of a Suspense Show, vaguely remember the opening ... can you help?
This was a very old TV show, probably from the 60's. Black and White.
It was an animated black and white opening with very rhythmic brassy cat and mouse kind of music where a shadowy dark male human figure was running back forth looking for something or trying to escape from somewhere, and everywhere it turned a black wall would appear before him and drive him the other way. The figure shrinks and looms like it is being surveilled or studied.
What comes to mind was "One Step Beyond" but it is not that I checked. I cannot remember anything other than the opening of this, and I want to find a YouTube clip so I can consider the music for a video I am producing.
