At first rather annoying in its heavy emphasis on reenactments, this movie ultimately proves fascinating, simply because the complicated, highly dramatic tale it tells still almost defies belief.

It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.

The acting is good, and the firecracker script has some excellent ideas.

Durably taut, but rather restraint little low-budget biological thriller that sees a group of scientists quarantined inside a building when a deadly chemical agent they're working on is accidentally released, causing them to become violently homicidal. Caught in the middle of it is a lady security guard, who might just hold the answer for a vaccine, as she seems unaffected.Confidently directed, thoughtfully written (as it could be seen as a minor blue print for "Resident Evil") and exemplary performed, but "Warning Sign" seems to go by unnoticed, despite it's considerably gripping and unnerving progression. Their low-scale origin is probably what tips it in that forgotten category, because it's not excitingly barnstorming in its thrills or cast. Nonetheless it bestows moments of furious intensity and compact suspense… in what feels like a waiting game after not taking all that long to get into it. The acting led perfectly pitched by Kathleen Quinlan, Sam Waterston, Jeffrey DeMunn, Richard Dysart, G.W. Bailey and Yaphet Kotto. Craig Safan chips away with an ominously airy electronic score. Director Hal Barwood well measured style, ably operates with his actors in constructing a real fearful mood inside the building, but also making the air outside just as dangerously on-edge. When it came to its irony enclosed ending, it felt a little out of place and rather forced than what it naturally built-up.An earnest, but well engineered sci-fi / horror outing that's more than your simple filler.

A small community in Utah stands by in disbelief and fear. There is a leak at Biotek, supposedly an agriculture research lab. These germs, exposed to the air, forces the ultra secretive building to be sealed off. Citizens want their loved ones rescued; not knowing that some are infected and are dropping dead. But, lo and behold, the dead are rising as berserk zombies. They become just as lethal as the germs slowly filling the building. The local sheriff(Sam Waterston) really has a hard task at hand, because his girlfriend(Kathleen Quinlan)is in there with the infected. Not necessarily suspenseful, the horror is minor; but the Sci-Fi flourishes. No great shakes. Others in the cast: Yaphet Kotto, Jeffrey De Munn, Richard Dysart and G.W.Bailey.

FINALLY I found out the name of this movie. I saw it alone in my living room about ten years ago, on t.v., and was so incredibly creeped out, especially when the scientists come on their "quest" after waking up. They acted so gentle, mild, yet we the audience knew that they were completely homicidal and insane, hiding axes behind their backs. Yikes!!!!! This movie came out at least a decade before 28 days later, another film I love, but Warning Sign was first!!!! Also, I love the fact that the enemies are formerly intelligent, successful people. always, the idea of people who you know and trust, changing into something evil is so disturbing to the human psyche. I've been searching for the name of this movie for so long, and finally got it by googling the actress, whose name I just happened to remember. Great movie!! very suspenseful and interesting.

In remote rural Utah a crisis situation transpires when a lethal experimental germ warfare virus gets loose in government Lab P-4 and causes the folks who become infected to degenerate into dangerous murderous raving lunatics led by Dr. Nielsen (robustly essayed by Richard Dysart). Gutsy, but frightened security chief Joanie (a fine and engaging performance by Kathleen Quinlan) is trapped inside with the deadly deranged crazies. It's up to Joanie's take-charge sheriff husband Cal Morse (superbly played by Sam Waterson) and bitter, boozy discredited doctor Dan Fairchild (the always great Jeffrey DeMunn) to rescue Joanie before it's too late.Director Hal Barwood expertly crafts and maintains an intense, nerve-jangling tone throughout, keeps the pace hurtling along at a steady, speedy clip, and delivers an ample amount of shocks while relating the chillingly plausible story. Furthermore, the barbed, incisive and provocative script by Barwood and Matthew Robbins offers a pointed and trenchant critique of government arrogance and incompetence alike (the government creates the problem and proves to be totally all-thumbs when it comes to properly rectifying it). Both Craig Safan's pulse-pounding score and Dean Cundey's polished cinematography are likewise up to par. The uniformly terrific acting from a bang-up cast warrants kudos as well, with especially praiseworthy work from Yaphet Kotto as ineffectual fed Major Connolly and G.W. Bailey as the bumbling nice guy lab employee who serves as the inadvertent catalyst for all the trouble. The fact that the main protagonists are a bunch of smart and capable adults rather than your usual array of dumb immature kids qualifies as another substantial plus; it's a nice and refreshing departure from the standard teen-oriented horror fare prevalent in the 80's. An intelligent, absorbing and above all quite suspenseful little sleeper that's well worth checking out.
