While Sandra Bullock's character clearly steals the show, the film is enhanced by some stellar supporting actors, including John Malkovich, who plays the irritating "survive at any cost" Douglas. While Douglas' character was made up for the movie adaptation, that didn't make him expendable — in fact, he ends up playing a pretty crucial role in saving Malorie and the children's lives, despite being doubted, hit over the head, and locked in the garage.
But while Douglas does end up being the reluctant hero, another aspect of his character is harder to tolerate: he's never wrong. Everything he says — which is almost always predicting some sort of horrible fate — ends up happening. He's against his wife leaving the house, and she dies. He resists allowing Olympia in, and she ends up letting in Gary. He wants to kick Gary out regardless of his groveling desire to stay and ends up being locked in the garage while the possessed man betrays everyone else in the house. Heck, even the fact that he was initially suing his neighbor Greg for wanting to build a glass house was the right call. Imagine covering up that many windows with newspapers without getting a glimpse of the monsters. Fat chance.
