Is "World Without End" on Netflix? I think at one point it was but I hadn't seen it in a couple years. (So I bought it on Blu-ray.) If it is on Netflix Canada, I recommend watching it. It's awesome. My mother even thought it was fascinating, and she and I typically have opposite tastes in movies/TV.
There is a website called 'JustWatch', which allows you to search for movies, and it will tell you what streaming service they are on (if any... includes Netflix, Disney+, Crave, Amazon, Tubi, Plex, etc.).
I did a search for World Without End... if it is the 1950s movie, it is not available on any streaming service.
