Stuart Gordon, Jeffrey Combs, and lots of gore is always a good combination. Worked in Re-Animator and works pretty well in this classic. From Beyond is the story of a couple Scientists that create a machine called the resonator. Well, the machine just happens to open up a door to a parallel universe full of brain eating creatures. In this scene, a transformed Dr. Crawford(Jeffrey Combs) sucks face with Dr. Bloch(Carolyn Purdy-Gordon) slurping her brains out though her eye socket.
Another good one is from this scene where Bubba, played by the great Ken Foree is devoured to the bone by tiny flesh eating insects that come out of the resonator. If he looks familiar, you may remember Ken from a little movie called Dawn of the Dead.
