If you want to get some information about any film, including cast, director, scriptwright, etc. I recommend you to use a good Internet Movie Data Base where you can find out almost all you need. Though there are lots of omissions in this datebase especially concerning non-American films but nevertheless it is very good and convenient to use.
Below there is a link containing scripts of several popular films. I found this one link with just movie scripts and it happened to be the most complete collection of them. New films are added there regularly. Most of them are of action genre that I don't like much. Other links I found contained almost the same scripts.

New reviews are added periodically. I hope you like these ones. So... I tried to write these reviews in form of description so it would be easier to understand what the film is about. Some of them contain quite a detailed plot. There are many sites of this kind but I like to read reviews or descriptions where author expresses his own attitude to the thing.
