Waxwork

wax museum in a small town is supposedly opening soon and invites some teens to a private showing, seeing numerous displays about various historical figures such as Dracula, The Phantom of the Opera, a werewolf and the Marquis de Sade. It turns out the owner is a practitioner of the dark arts and each display is actually a pocket dimension with actual artifacts from the actual historical monsters. Whenever someone steps into the display, they are pulled into the world of the monster and killed. When a victim dies in that world, he turns into a wax figure in the monster exhibit.
