Army of Darkness
Ash Williams, horror's greatest hero, is accidentally transported to 1300 A.D., where he must battle an army of the dead and retrieve the Necronomicon so he can return home.
After defeating the deadites in that cabin in the woods, Ash winds up in medieval times (the time period, not the restaurant). With his trusty boomstick by his side, he must send the armies of the dead back to hell, and vanquish the villainous Bad Ash. Groovy.
