Will I learn a different language by just watching movies with English subtitle?

I study Spanish as a 3rd language. I only watch Spanish movies with English subtitles. You will be surprised how many words you add to your vocabulary, but I don't think that will be enough. I did a beginners course, use google translate and duolingo randomly to practice using 3 of the skills. Next step will be to get an online Spanish tutor to practice my speaking skills. You might get discouraged if you only try one method.

Met quite a few people that managed to do that but they were exposed to the language daily. They actually live in that country this particular language is used.

You need to do more than just watch movies with English subtitles. You can also learn by watching movies in English with subtitles in your mother tongue or English movie with no subtitles at all. In the end none of the above will help you with improving your speaking ability, only speaking will do that. You need to write, speak, listen, and read in order to learn a new language well.

yes at some level
