Were there any actors who didn't become famous because they missed out?

There were many actors who did not become famous because they missed the opportunity. For example, some actors might miss the opportunity to become a big star when they first debuted for some reason. Or some actors might not be widely recognized by the audience because their acting skills were not good enough or their appearance was not outstanding enough. Therefore, these actors might need to work harder and improve their acting skills in order to obtain more opportunities and success in their future development.
