We do tend to focus on TCM movies (and present ones) that achieved a certain level of popular appeal. Of course, most of them are from the black and white era. However, there are so many that Hollywood produced that, indeed, most of us have never heard of. Sometimes I will search out obscure movies starred in by some of my favorite actors. I also try to notice the names of unheralded cast members and then search for them on the web to see what happened to them. I guess that when they were awarded a part in a movie that they thought they were on their way to stardom. Of course, that's also true of today's actors.
