Along those lines, there's a small French 100+ year old language learning company called Assimil [1]. They're universally beloved by polyglots [2] [3]. They make courses out of clever dialogues with your First Language on one side and your Target Language on the other. The courses come with audio for your Target Language. They're cheap, around $50-$100, and packed with enough information to bring a total novice to respectable intermediate status.
I used their English-Spanish course to learn Spanish extremely quickly. After a few months of study, I was able to watch native Spanish TV programs with Spanish subtitles and understand 80-90% of them. I would emphatically recommend their method to anyone. I am not affiliated in any way with the company.
There's also the Listening-Reading method, which many polyglots swear by, once you've gotten your bearings in your Target Language. It's a rigorous but fun method of learning your Target Language by enjoying audiobooks of your choice.
Incidentally, it is wise, if you're serious about learning a language quickly, to seek polyglot forums and to use their accumulated knowledge to smooth the path ahead of you.
