The thick plot that this movie boasts, combined with (in my opinion) Sly Stallone's best performance as a professional actor, places "Lock Up" amongst the elite films of our time. It is almost impossible for the viewer not to feel Leone's utter pain and frustration, and by the time the movie has ended, to feel as if he or she, too, was locked up. There is absolutely nothing that this movie lacks...great acting (Stallone is brilliant), pure drama and emotion, and above all else, excitement. Seeing Leone single-handidly take over the prison football game is an image that will remain with me for a long, long time. Furthermoe, Donald Sutherland is equally impressive in a lesser role. The initial meeting between he and Leone is bone-shaking, as Sutherland proceeds to utter the infamous greeting that sets the tone for the flick..."Welcome to Southgate, Leone..." and with that, the viewer's journey through teror, tumult, and ultimate victory has begun. It is a complete shame that this film was not recognized as one of the best of its day. In my opinion, critics of the late-eighties were not ready for the State-of-the-Art performance put forth by Stallone, which set the way for other movies in the near future. Truth be told, Stallone revolutionized the role of the actor in "Lock Up", and it is about time that he recieve his well-deserved due.
