English in Movies

How to understand English Movies without subtitle. I am the one who loves to watch foreign movies with soundtrack. I think it gives more feeling than interpreted films. I think watching movie without subtitle is better, it's so interesting. But I am not a professional who experts in English language . Another skill that I need is listening. I try hard to listening and think follow it. But I think it's not enough. Are there any else ideas you would like to tell me??
