Nicole Kidman' Carol Bennell must stay awake or she will be absorbed into the collective which is controlled by an invading virus that travels to the Earth on the back of an ill-fated space shuttle.
Kidman attempts to protect her son Oliver (Jackson Bond) who is marked for assassination by the collective because he can not be assimilated, but the former husband who wants more time with his son is an early convert to the control of the virus and places Oliver in danger.
Psychologist Bennell has a client Wendy Lenk (Veronica Cartwright) who believes her husband is not her husband. It may be difficult for humans to recognize the zombie like characters but dogs quickly know something is rotten with many of the folks in town.
While the kids sit in front of the red door discussing dad's strangeness a woman moves from car to car saying "there coming." Colleague, Ben Driscoll (Daniel Craig) brings Bennell home to meet mom and dad who turn out to be warm interesting folks until the change grabs them.
Its obvious this is a remake of the effective science fiction film Invasion of the Body Snatchers from 1956 with Kevin McCarthy and Dana Wynter and the very successful 1978 remake with Donald Sutherland, Brooke Adams and Leonard Nimoy. But here director Oliver Hirschblegel has Kidman running down streets, in traffic, up stairs, down stairs and into dark cellars, rather than creating a dark frightening scenario.
Jeffrey Wright's Dr. Stephen Galeano is the guy in the lab who is feverishly working on the antidote which can save the world. Of course Kidman's Bennell gets spit on and is attacked by the virus. Because she knows REM sleep is when the virus takes control she spends her time popping pills and drinking caffeine filled soft drinks like Pepsi.
The numerous flash forwards which are designed to peek attention simply confuse and the immediate peace that overcomes the world is almost comical and similar to the effect of the 1934 Death Takes a Holiday in which Frederic March is death on holiday and no one dies.
This is more like Terminator stuff filled with car chases and burning cars careening down streets. It only relates to us when a tired, drowsy Kidman fights to stay awake - the same thing happens to us while watching Invasion.
