### Review:
Deliverance is a stunning thriller, every bit as exciting as any good thriller should aspire to be but also stomach-churningly frightening. Though it is not a horror movie, it is just as terrifying as any classic horror film. The very thought of being a normal red-blooded male enjoying an adventure weekend miles from any form of civilisation, only to be captured and sodomised by a couple of violent hillbillies, is surely the worst nightmare of 99.9% of the world's population. It would have been easy for Deliverance to slip into exploitation territory, but John Boorman has cleverly avoided the temptation to go down such a route and has made a film that explores, questions and challenges the very meaning of masculinity. With so many films, you come away wishing to heaven that you could step into the hero's shoes, performing heroic deeds and saving the day and getting the girl.... but with Deliverance, you come away praying to God that you'll never have to experience what these four protagonists go through.<br /><br />Four city guys - Ed (Jon Voight), Lewis (Burt Reynolds), Drew (Ronny Cox) and Bobby (Ned Beatty) - head out into the wilderness to spend a few days canoing down a soon-to-be-dammed river. The guys are riding the rapids in pairs, and Ed and Bobby inadvertently get a little too far ahead of the others so they pull in to the riverside and await their pals in the adjacent woodland. Here, they fall foul of two local woodlanders (Bill McKinney and Herbert Coward), who tie Ed to a tree, while one of them strips and rapes Bobby instructing him, perversely, to "squeal like a pig". Lewis and Drew arrive unseen and Lewis, being a fair archer, kills the rapist while the other hillbilly beats a hasty retreat into the forest. Under great emotional stress, the four canoeists decide to conceal the event and get out of the area. But they find the river increasingly dangerous to negotiate as they journey downstream, and the risk to their lives heightens when the surviving hillbilly returns to take shots at them with his rifle from some unseen vantage point in the rocky cliffs beside the river.<br /><br />Deliverance is very powerful as a survival tale, but even more powerful (and disturbing) as a study of macho attitudes being torn apart and left in humiliated tatters. Though all the performances are remarkable, one must take particular note of Beatty's efforts in a role that many actors would've turned down. The film is very similar thematically to the 1971 film Straw Dogs - both films deal with terrifying sexual violence in isolated locales, and in both the eventual violent revenge exacted by the victim does not result in any sense of satisfaction. The backdrop of the rugged countryside in Deliverance is beautiful to look at, but it also adds to the tension by placing the four canoeists in a setting where they are at the mercy of the hillbillies and the landscape, with nobody to rely on other than themselves. This truly is suspenseful film-making at its finest.
