Was This an Episode - Man Trapped in Well That is Then Filled with Water
I am not sure if this was a Twilight Zone or Outer Limits episode. It may have been some other show entirely. Saw it is a kid in the 60s.
Just recall bites.... A man enters a sort of western town... its empty... he falls into a deep tank or well. He has been trapped there by another man who can see him through a camera at the top of the hole. Slowly the hole is filled with water...
Ring a bell?
