Humour and irony make it good
Frankly, I was surprised to know that this movie was directed by George Cosmatos, the creator of such action films as Rambo-2 and Cobra. `Of Unknown Origin' is an absolutely different one. I found it interesting and amusing. It has everything that every good horror film should have the spirit of suspense. Of course, Peter Weller acts very convincing. I think the movie wouldn't have its strange and surrealistic atmosphere without his talent of acting. The most remarkable episodes include one with Weller talking about the problem of rats in the US during the dinner with his boss. But as a whole I would say that what makes `Of Unknown Origin' a good movie is humour and irony, which one can easily trace from the beginning till the end. I would recommend this film for those who like horror movies not only because of special effects.
Not to be Underestimated!
This movie is about a large, smart rat threatening to undermine everything a worldly wall street climber (Peter Weller) has worked to create for his world. The movie is like it's clever rat...creeping up with more intelligence than should be expected.
Great movies work equally on separate levels so that a wide audience can take what they will from it and still enjoy it immensely. Although technically a B-movie punctuated by 80's camp, it is unmistakable that "Of Unknown Origin" is truly special.
It's unfortunate that this movie has enough unattractive elements to deter a viewer's interest. First of all, it's a "rat movie". When has that ever been a favorable genre? Second of all, Shannon Tweed's involvement, however early in her career, emits an odor of genericness and illegitimacy.
Don't be turned off by all these potentially fatal bad traits. Director George P. Cosomotos and Peter Weller had an interesting, artful collaboration going on in "Of Unknown Origin". The film has a tight focus on theme and story, and goofy, highly entertaining, cult-status-worthy performance bits from Weller. It's a fun film- there's no doubt about that. There may be cheese, but there's also sincerity in how the film refuses to take itself seriously. Also, the familiar moral of the story is shown in so fresh a form that you won't even care.
For a story that works so well on an intellectual level, it's a blessing that the actual rat combat scenes are a great time. As Weller's lost yuppie starts to lose his sanity, his battles with his furry foe become more and more extravagant. Let's just say the conclusion is incredible.
The title refers to the clouded evolution of rats. It also speaks of the burning, unavoidable core of our hearts that is pure and determined to defeat our dark sides. Our consciences? Our God? Or is it just a fear of a big friggin' rat? Ponder that if you'd like, but enjoy "Of Uknown Origin" regardless.

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.
Of man and rat
This is the story of a man (Bart Hughes played by Peter Weller) who becomes obsessed with a little rat problem he's having at his newly renovated house. Instead of focusing on Bart's growing insanity, the director unfortunately showcases the rat as a vicious and dangerous beast. Although there are some quite effective closeups of the rat-villain, we never really feel any threat emerging from this little creature. Bart's obsession seems all but unbelievable. It's implausible that he would not just move to a hotel or try (harder) to contact an exterminator. Also, the movie just doesn't seem to have any real purpose. After a quick showdown it just ends, leaving some plot lines (Bart's job, his relationship to his family) unresolved.
"Of Unknown Origin" is still a very watchable movie. The pacing is quick and Weller does a pretty decent job in this one man-show. Had director George P. Cosmatos added anything to make it more than a mere monster movie, "Of Unknown Origin" would no be the obscure left-over from the early 80's that it is.

The Rodent Jaws
Peter Weller anchors a cast of Canadian actors in this entertaining low budget thriller directed by George Cosmatos. Plenty of action and a good through line of how an obsessively detailed individual would battle a threat to his environment. Louis "Seeing Things" Del Grande is very good as the helpful janitor next door to Weller's yuppie palace. Features rising Canadian actors Kenneth Welsh, Jennifer Dale and a slimmer Maury Chaykin. The Canadian Tax Credit system helped put this film in Montreal, doubling as New York. With little to work with in terms of sets and exteriors, Cosmatos shows his chops as a director who tries to make each shot pay off in a particular way. The overhead shot of Weller looking out over the "human" rat race crossing the street draws an interesting parallel with the main story. More than a couple of 'homages' to Jaws, which Cosmatos admits was one of his favourite movies.A bit repetitive at times but better than 'Willard'. Worth a look.
