Bah! Kids these days, they think they invented zombies! Why, they don’t know what us old-timers had to do to see a zombie flick. Up hill in the snow both ways, barefoot, just to see something made in Mexico! Also known, unsurprisingly, as Cementerio del Terror. The IMDb plot description:

A professor suspects that a vicious killer may have discovered a way to return from the grave and continue his violent spree. His fears are proved true when a group of teenagers decide to pull a Halloween prank by stealing the killer’s body from the morgue. When the teens recite an incantation from an old magic book over the corpse, it begins to come back to life, along with all of the bodies from the nearby cemetery.

The second feature on the double-feature DVD is Grave Robbers (1990), aka Ladrones de Tumbas, which is at least passingly similar in plot to the first movie: Teens, grave, killer zombie. Only one, but he makes up for it with enough of a body count that some people describe Grave Robbers as a zombie/slasher hybrid.

From Brentwood Home Video, so no extras mentioned and none expected. $12.99 from Amazon.com. (Ignore the production dates and plot descriptions from Amazon; they obviously think they have better things to do than ensure accuracy in their zombie movie sales copy.)
