    I am adopting cats.....yesterday!

    I give this one a ten. How? Well, if you love rats, you will hate me. Let me just start off by saying I have never written a public comment, so do be gentle. I am also rather desensitized to horror films. Salo, Irreversible, and others I am ashamed to mention, hardly phase me. I've seen other rat films. Older rat films, and new ones haven't bothered me. I had purchased this film with about 20 others, and it looked silly, was inexpensive, so why not? I find myself awake this morning at 4:30 am, and in need of mild entertainment. Here is where my horrific morning begins.

    I am a 24 year old female, so to all you guys reading this, never show a woman this movie. Show her Cannibal Holocaust, not this. I slap in my DVD of this film, pull my covers back and wait for 90 minutes to pass. 10 minutes later I am screaming like a wild woman being attacked by the Texas Chainsaw Massacre. This movie is INSANE! I own 1000 horror movies, and I thought I had built up enough tolerance and desensitization to endure any form of human torture. Wrong! This is one evil, hideous, demon possessed rat. By the time an hour had passed I was clutching on to my baseball bat, and wouldn't you know? A shadow from my ceiling fan caused a sharp movement on the floor., and I was running down my hall in a terrified frenzy. It may be that girls like me just can't cope with a rat, but it might just be that this movie is hell bent on preying on everyone's natural dislike for these foul little beasts. I sat and hoped that WHAT I KNEW WOULD HAPPEN…would not. It did. I was so happy when this movie was over, but ever happier I gave it a chance. It is rare I feel fear, and this was a great reminder. It isn't Citizen Kane, sure, but it is more entertaining. It is my worst fear, realized. Except for that whole broom in girlie prison thing. I digress.

    I know you guys are tough! I know you ARE THE MAN! BUT! If you can make it through this movie without jumping in your seat, well, you should join the Navy Seals. Or better yet….you would make a great executioner. This is a nerve wrecking modern spin on MAN VS. MONSTER. No kidding!

    This movie gets a ten from me. After sitting through 1000 movies that people say are scary, I find this fabulous little gem, and come to realize just why I love horror. This is horror. Nobody gets tortured, raped, or beheaded. That is fine, considering how brilliantly the film makers took a simple fear and found a way to torture the audience, and not one lesbian bimbo vampire was skinned alive. I was impressed.

    I wish I was so well versed and I could give you the most complex analysis of the technical specifics. I am not. Peter did a great job in being convincing, and some of the camera work is great I think. The camera often acts as the eyes of this evil monstrosity. The mans wife in this movie is really pretty, and you see her boobs. So, you guys might like that if nothing else. I think the film was very well done, and most effective at making it's point. I would tell you all about the shocks, but that would ruin them for you. Some must be seen to be believed.

    I'm a girlie girl, sure. I bet you can't make it through this movie, in the dark, without your baseball bat either. If you are on the fence and wondering if you want to give it go, do it. But, remember, it can bring out your feminine side. Isn't that the definition of scary for you boys?

    Either way, for my own sanity,I am adopting a cat today.

    Imperfect, but effective little thriller

    The premise of this film isn't exactly original, but a story like this has great potential both for a psychological thriller and for a fun horror flick...but unfortunately, Or Unknown Origin doesn't quite manage to excel at being either. The focus is more on the battle between man and rat than providing the sort of schlocky horror that the eighties produced so prolifically, which is fine; but it never probes too deep into the psyche of the central character, and the film plays out like a movie that should be fun, but largely isn't. That's not to say that it's a bad film, however, as there are a lot of good ideas on display, and the film also features what may be a career best performance from Peter Weller. The plot sees a man who recently completed the rebuilding of a house being left alone when his wife and child go on holiday. He stays behind to try and win a promotion, but he doesn't count on an onslaught of torture when it turns out that the house he put together has become infested by a rat. What follows is an all out war between man and one of the world's most notorious pests.

    Rats are one of horror cinema's most popular animals, and it's not hard to see why. There is a scene in this film that sees the central character make a case against rats, and it really makes you realise the reason why these animals are so often feared. Of Unknown Origin starts out slowly, but builds some momentum half way through when our hero begins his personal war against nature. I wasn't expecting much after the first half hour, but the film surprised me somewhat by the way it eventually comes together, climaxing with an exciting sequence that sees the central character really go off the rails. Peter Weller really is superb in the lead role, and I wouldn't be surprised if this film was the reason he went on to take the lead role in the classic Sci-Fi thriller 'Robocop'. It's a shame that director George P. Cosmatos doesn't seem too keen to get fully inside the character's head, as the potential for a great psychological thriller is definitely there. This film may have been better if it was handled by someone like David Lynch, but despite its imperfections; Of Unknown Origin is still worth seeing.

    Just When You Thought It Was Safe To Go Back Home - JAWS the Rat. 1-2-Watch

    Greetings And Salutations, and welcome to my review of Of Unknown Origin; here's the breakdown of my ratings:

    Story: 1.75 Direction: 1.25 Pace: 1.25 Acting: 1.50 Enjoyment: 1.50

    TOTAL: 7.25 out of 10.00

    This little creature feature flick had me surprised. Delightfully surprised. For one, the story is incredibly potent in its credibility. It not only deals with a rat infestation but the troubles it can cause, let alone the physical destruction there's the mental assault to consider. Secondly, the direction is on-point and commendably captures the events as they unfold. And thirdly, the acting is excellent.

    Everything should be grand in the life of Bart Hughes. He's successful, married to a beautiful woman, has a marvellous son, and has just finished renovating his new city home. Life is paradise until his wife takes their son to the inlaws for their annual few weeks' vacations, and ratty the rat starts scurrying behind his expertly plastered walls. In a few days, Bart's life spirals out of paradise down the plug hole of hell. Since this is a story about one man's battle against a rascally rodent, it's nice that Brian Taggert made it more of a character-driven piece. Doing so allows the audience to place themselves in Bart's shoes. It also enables his breakdown and mental deterioration to be displayed thoroughly. And, I have to say, Taggert handles it superbly. And though the times get harrowing for Bart, Taggert peppers in some humour to keep the audience's interest. Another plus is the use of facts. We see Bart head to the library to gen up on his enemy. What he learns is shocking and more than a tad disheartening. But this is genuine information compiled from reliable sources and not something the writer dreamed up. This realism adds to the credibility of the story.

    George P Cosmatos is a decent filmmaker and tells Bart Vs Ratty faultlessly. He adds some appealing and stimulating camera angles, though he chiefly employs a standard point-and-shoot style, with some fine compositions and steady pans. He also utilises natural light and shadow, which adds to the realism of the story and movie. Additional potency could have been created by increasing the number of engaging angles and scenes. There are plenty of opportunities to display the damage the rat had wrought. Had these been captured in a more striking style it would have only strengthened the picture.

    This movie is Peter Weller's, and he should be proud. That's not to say the rest of the cast are rubbish; on the contrary, they are superb. But this story is about one man versus one rat. And that man is Bart Hughes, portrayed exceptionally by Weller. Weller gives the ideal presentation of a man who has an unspoiled life. And as we progress through poor old Bart's trials and tribulations, Weller, by turns, takes him deeper and deeper into the darkness of anxiety and depression and obsession. It's a great depiction of falling down the rabbit hole.

    And, for that alone, I would gladly recommend Of Unknown Origin to every movie watcher. It's entertaining, credible, full of realistic characters, exemplary acting, and admirably filmed.

    Now, if you've set all the rat traps, get your arse over here and have a gander at my Absolute Horror and Monstrous lists and see where I ranked Of Unknown Origin.

    Take Care & Stay Well.

    There's a rat in mi kitchen, what am I gonna do?

    It's (future) Robocop VS. Rodent in this interesting & compelling but ultimately bland hybrid between an ordinary creature feature and a portrait of psychological downfall. Textbook 80's yuppie Bart Hughes has everything you could wish for in life. Married to the previous Playmate of the year, he owns a personally renovated brownstone in the heart of New York, his parents-in-law live all the Vermont, his secretary has a not-so-hidden crush on him and he's moments away from getting that important assignment everybody at the office was craving for. Bart's perfect universe gets brutally disturbed when an unusually intelligent rat decides to join the household and run a little bit of amok in the house. When all regular rat-catching methods like traps and poison fail, Bart begins to take the battle personal. He gradually goes berserk, isolating himself from his colleagues and neighbors, with only one mission left to live for: annihilate the rat! Okay, what we have here is an ambitious script about an alarmingly escalating obsession, a stellar performance by Peter Weller and skillful photography by René Verzier who successfully manages to depict the ordinary rat like the most fierce and petrifying monster in the universe. That's very admirable and all but, in the end, "Of Unknown Origin" only just remains a film about a guy chasing vermin through the house for nearly 90 minutes. The rodent's intellectual capacities, as wells as some of Bart's desperate measures to catch it, are just a tad bit implausible and actually on the verge of hilarious, even though the whole thing is acted with straight faces and serious undertones. What type of rat are we dealing with here, in fact? Because sometimes the animal is small enough to move through the draining pipes whereas at other times it looks big enough to pass for a warthog. Or maybe its variable sizes were intentional as part of the whole psychological aspect, and then I missed the point again? I know "Of Unknown Origin" isn't meant to be a full-blooded horror film, but still the lack of blood and action was mildly disappointing. Couldn't the rat have killed the irritating neighbor, the exterminator or even Shannon Tweed? Unquestionably the most fascinating moments of the entire film are the rat trivia Bart recites to all his clearly embarrassed colleagues & superiors during a diner party. Now that scene was both creepy and educational.

    One of my all time favorites!

    Of Unknown Origin is an overlooked gem of a little movie. Not really a horror film, except that something does indeed go bump in the night, and often too. No, this is more of a psychological drama and Peter Weller bangs one out of the park with his performance as the yuppie forced to go to war with a rat. The movie gets down right primitive and to the point, and it's all Peter Weller and some excellent rat photography. I watch this movie about once a year and it's one of my all time favorites. The film isn't dated and the dvd transfer is good so check it out if you're looking for something a little different, something of quality, and not your normal run of the mill mindless horror flick.
