Come in - if you dare. The opening-night gala for a new exhibit at Chicago's Natural History Museum is under way. But be advised: something terrifying wants to make sure no one ever leaves. Penelope Ann Miller, Tom Sizemore, Linda Hunt and James Whitmore star in this effects-packed shocker that gives haunted-house movies a terrific new setting. And the non-human star (brought to head-ripping life by Jurassic Park Oscar winner Stan Winston) is something no creature fan can let slip by.
