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 terrifying 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 slip by.
