Modern vampires come in many guises, but they all address our fascination with sex and death. From the ghastly Count Orlok to the glam vampires of True Blood, John Landis, Josh Hartnett, Mick Garris and others take a look at why thirsty fiends are endlessly appealing.

Ghost movies have been with us since the dawn of cinema. Some ghosts are benevolent, some ghosts are malicious, but they all represent the mystery of what happens to us after we die. Stephen King, Haley Joel Osment and others break down the appeal of spooky spirits.

The fear that demons will enter our bodies and make us do terrible things has inspired some of the most frightening films ever made, including the masterpieces Rosemary's Baby and The Exorcist.
