As well as watching English movies etc, I suggest you use websites that have audio and transcripts available. You can then listen and read the transcripts aloud to practice your pronunciation. For example, you could watch a music video that has lyrics written for you to follow or major news websites that help English language learners.

Hey. English videos (documentaries, movies, youtube, just everyday talk) are very precious resource. It helps tremendously to improve your pronounciation, it makes you familiar with many often used structures and words. It gives you patterns that u can build on later. It doesn't even matter how good or bad you are but the more you listen the more confident u get, and more familiar with the sound, or 'vibe' of a language. That's what I think.
