The world might end, again.
There is a laboratory in the middle of the desert. While everyone thinks that the lab is developing pesticides, it is actually a secret government facility where the scientists have developed a chemical that will turn anyone exposed to it into a homicidal maniac. While the scientists are celebrating the success of their project, Dr. Tom Schmidt (G.W. Bailey — yes, Captain Harris from the Police Academy movies) steps on a vial and releases the chemical. The lab locks down and the army (led by Yaphet Kotto) arrives. The government wants to let the scientists kill each other off but a pregnant security guard (Kathleen Quinlan) is also trapped in the lab and her husband, the county sheriff (Sam Waterston), is determined to get her out.
Warning Sign was blandly directed by Hal Barwood, a longtime associate of both George Lucas and Steven Spielberg. (Barwood wrote the script for Spielberg’s The Sugarland Express and designed the title sequence for Lucas’s THX 1138.) Barwood tried to take a very Spielbergian approach to Warning Sign, a mistake because successfully imitating Spielberg is easier said than done. Replace the shark with germs and the ocean with a lab on lock down and Warning Sign is like Jaws, without any of the suspense or humor. Sam Waterston’s germaphobic sheriff feels like a knock off of Roy Scheider’s aquaphobic police chief while Jeffrey DeMunn, as an alcoholic scientist, stands in for both Richard Dreyfuss and Robert Shaw. With the violence and the gore kept to a minimum, this is one of the most tasteful zombie films ever made. Just compare it to George Romero’s The Crazies (or even the remake) to see how needlessly safe Warning Sign is.
