Cop Land

This is one of Stallone's best acting jobs.  Just listen to his voice and how high pitch it is compared to other roles.  Stallone has a naturally low voice, so he had to make his voice sound higher to make his character seem scared and weak.  And you believe it which is hard since Stallone is one of the greatest badass action stars ever.  Ray Liotta is also great in this movie.  He plays an intense role that is obviously messed up.  All of the supporting cast is very strong and play well off of each other.   The story is interesting and has lots of twists and turns.  Overall it is a really good movie, with great acting, and an ending that is really awesome.
