These worms are out for blood! The foul-smelling, human-chomping "Graboids" worms from the comic sci-fi flick "Tremors" are back again - and nobody's safe. This time, though, they've mutated and shrunk a bit, but it turns out that smaller means even deadlier in "Tremors 2: Aftershocks" (1996). But once again, Fred Ward as Earl Bassett is on the scene, ready to take on those grabby grubs, with the help of sexy geologist Helen Shaver and Michael Gross, his pistol-packing partner from the first funny flick.
