This movie was pretty good. Robert Redford is an ex-general who is given a long prison sentence in a military prison because he led a faulty mission that ended up with several soldiers killed. It turns out that it was never his fault, but he ends up going to this prison anyway. Throughout the film, he tries to rally other prisoners behind him and rebel against the brutal prison warden, who has killed many prisoners (and makes it look like an accident). It is supposedly called "The Last Castle" because while most castles made in the last few centuries were built to keep people out, this prison castle was built to keep people in. This was good and exciting and the explosive action scene at the end is definitely worth the rental fee by itself. Feel free to email me with any questions or comments.
