Prisons are not exactly renowned for their kind hospitality and 'happy vibes', what with stories of fights, chaos, murder and of course extreme male bonding! But the prison in this film is a different beast altogether. Horror films set in cells are, as you probably know, nothing particularly new as they emphasis and exaggerate the fear of claustrophobia and the inability of escape  two of the greatest themes in horror cinema. With such examples as THE CHAIR (Waldermar Korzeniowsky, 1988), THE GREEN MILE (Frank Darabont, 1999), ALIEN 3 (David Fincher, 1992)and of course the entire Women In Prison exploitation genre itself, another entry into this niche has to be something inventive and a lot of fun to boot in order to be recognised. Or at least that's what you'd have thought. PRISON is certainly an incredibly fun and enjoyable ride and it's somewhat of a shame that it isn't as well known as it should be.<br /><br />The film, in short, centres on an old prison (well, duh!) which has been reopened. However, it's not just fellow inmates and guards the prisoners have to fear, but also a mean ass demon ghost spirit with only one thing on its mind; death! And boy, are we treated to some awesome death scenes! I won't spoil anything here for you but there are plenty of innovative and enjoyable murders all done by invisible hands.<br /><br />Besides the special effects and the murders, this film also has another thing going for it; it's cast. Headlining, we have LORD OF THE RINGS (Peter Jackson, 2001-2003) star Viggo Mortensen (and for all those so inclined, yes, he does get naked) whose performance is not only highly believable, but is done with such skill that his Eastwood-esquire character is both bad-to-the-bone and likable (a very delicate mix). Add him to a cast of 'hey-wait-a-minute-I-know-that-guy' actors and you've got yourself one great set of stars. The characters themselves however lack three-dimensionality and more often than not come across as very stereotypical. We've got a black oculist, a hard-as-nails prison warden, a human-rights activist woman and plenty of other stock characters. But in all honesty, this 'fault' actually aids the film. Instead of boring character development in an over-long equilibrium, we are chucked, more or less, straight into the action and once it gets going (very early on) there's not a single scene that's a filler  it's balls to the wall plot. Unlike a certain SHAWSHANK REDEMPTION (Frank Darabont, 1994 )! Sharing conventions with the slasher genre, this is somewhat of a convention itself, and, in good ol' slasher genre tradition, PRISON punishes those who have been bad.<br /><br />All in all this is an excellent little horror film and one which is sadly overlooked and unmentioned among the horror world. With an excellent cast and great special effects and rather original death scenes this film is highly recommended to horror fans. Don't be fooled into thinking it'll be a cheesy little film either, just because it was made in USA 1980s, it's far from cheesy (although the very end does ruin this) and, simultaneously, far from gritty and realistic (whilst it attempts to tackle issues such as prison rape, these are rather subtly done).<br /><br />I give it 3.5 out of 5 luvs. A very entertaining horror film with some very nice touches indeed.
