Obscure but reasonably solid exploitation effort from the early 70's with a plot and character drawings that actually qualify as disturbing. Undeniably influenced by a number of gritty contemporary survivalist- thrillers, such as for example "Deliverance" and "Straw Dogs", the film narrates the compelling plot about three seemingly ideal and loving family men and their rather unusual annual tradition. Once a year Ken, Greg and Art – three college football buddies and Vietnam veterans – go on a "camping trip"; basically only to do all the nasty stuff their wives and fellow community members would never see them capable of doing. We're talking rape, kidnapping, humiliation, vandalism, extortion and a virulent game of hunting-humans. In the opening sequences already, some college accused the trio of gang-rape, but the school principal made it clear to the girl's mother that the reputation of the trio is stainless and undisputed. During this year's trip, they abducted an adulterous couple and got rid of their car. The unsuspecting victims are subsequently taken to an island in the middle of giant lake, toyed with for some more time, and then 'released' for the hunt. Although influenced by the aforementioned backwoods-survivalist thrillers, "Open Season" is primarily another re-working of the classic and legendary film "The Most Dangerous Game". It's a tense and disturbing film, for sure, but I'm under the impression that it could have been even better. The middle section is slow and even somewhat dull, only because director Peter Collinson insists on emphasizing the anxiety and troublesome position of the hostages. There's also quite a lot of pointless footage of the three anti-heroes boozing and hunting, apparently just to state clear once more that they're mean and ruthless guys. Okay, we get it now! Luckily enough, the wholesome is saved by the virulent climax (hooray for William Holden, as he shows up as one of the previous victims' father out for revenge) and the outstanding acting performances from the entire cast. Peter Fonda, John Phillip Law, Richard Lynch, Alberto de Mendoza and William Holden together in one and the same film makes it absolute priority viewing for every self-respecting cult cinema fanatic.

Get some decent Americn actors on the cheap, film in the mountains outside of Madrid to cut expenses, play it for the U.S. market and you end up with this film. I think that is the main reason so many male reviewers on this site think this is a terrific film. Because of the European sleaze factor of one pretty single woman in a mountain cabin with men with guns. The plot has been explained by many others but (Spoiler alert) most missed the fact that Fonda had fathered a child years earlier when he and his "clean-cut" pals gang raped Holden's daughter and got away Scot-free. That's why Holden shows up at the end to exact revenge and to stop these guys. I just watched a tape of it and am selling it fast and cheap so it won't contaminate my library of films.

Open Season is a terribly unpleasant melange of The Most Dangerous Game and Deliverance. It was a critical and commercial flop in its day, and was further criticised for wasting the talents of some usually reliable actors like Peter Fonda, William Holden and John Philip Law. I'm a fan of William Holden, and as a completist I was eager to seek out the film. However, having finally tracked it down and watched it, I can honestly say that it was not worth the effort. This is a poor movie indeed.The wafer thin plot has three ex Vietnam vets heading off in the autumn to their remote hunting lodge. En route, they kidnap a young, romantic couple and imprison them once they reach the lodge. After fattening them up and sexually degrading them, the delightful trio turn their prisoners loose and pursue them to their death.The plot is such a nasty concoction of themes that it needed sensitive handling to avoid becoming an exploitation piece. Peter Collinson directs with a sledgehammer, stripping the film of any dignity that it may have had and making it a truly horrid little item. The arrival of William Holden at the end, in a half-decent climactic shootout, is the only moment that the film comes to life, but by then most discerning viewers will have bolted for the exits (if in a cinema) or pressed the stop button (if watching a video or DVD). Open Season is a bad, bad film, offensive and unpersuasive throughout and utterly deserving of all the negative reviews it has received over the years.

This film was different, but very good. The beginning was interesting, and Peter Fonda played really well, he made this film worth watching. Although he was a "bad guy", he had a certain hidden charm. I wish this film would come out on DVD, so I could buy it.
