In my opinion, conversation is essential to gain fluency in a language. Passive activities like watching movies are not effective uses of a person's time. Reading is also important, because it will help a learner to attain fluency in the most difficult area: writing.

Correction (I think): "How can I become fluent in English?" Is it only through conversation?" Answer: Probably because you will learn how to effectively communicate in English. Textbook English is hardly spoken.
