Are there any movies which could help me with my English? I think listening is an important part of learning English, so I want some movies with clear pronunciation. English has a great many regional dialects. The English spoken in American differs in pronunciation and spelling to the English spoken in the England and Australia. Canadian English sounds similar to the English spoken in the northern part of the US. In addition, England and the US have many regional dialects and some of those are almost unable to be understood by other English speakers. So you have a problem on your hands - which version of the English dialect should you choose ? For UK English, find documentaries from the BBC. For American English, look for news broadcasts from CNN or PBS as the sound recording is of better quality.

Oh, these are not movies, but David Mitchell produced a lot of short videos in youtube and his pronunciations are very good.

"I want some movies with clear pronounce" For "English" English, perhaps the voice of Jeremy Brett in the "Sherlock Holmes" series? (http://www.bilibili.com/video/av1154999/) and the rest of the series and seasons. and the more "modern" Sherlock (Cumberbatch). (http://v.youku.com/v_show/id_XNTE3NTU5OTky.html).

Yes, a lot of movies actually use slangs and slurs that are present in everyday life to make them sound more authentic. It is going to sound less clear in terms of pronunciation. What sort of movies are you into? I think I've not watched movies in a while, but the last few X-Men movies don't have a very thick modified English accent, if I remember correctly. How about watching talk shows, though? I watch shows like QI and 8 Out of 10 Cats. Jimmy Carr enunciates his words very well, even though the rest of the people in his panel speak in accents usually (with Sean Locke being the clearer one to understand).
