The Beast from 20,000 Fathoms (1953)

The 20,000 Fathoms part of the title isn’t very relevant, but the Beast part certainly is. Stirred from slumber by scientists testing atomics somewhere in the Arctic, the creature causes havoc as it makes its way purposefully south. I don’t appreciate being rudely woken up, either, so I can kind of relate.
The script, 'suggested' by a short in Ray Bradbury's The Golden Apples of the Sun (1953) collection, toys with the psychology of witnessing the impossible, while exploring a more elaborate scientific reasoning with regards what's actually seen. But the best part of this particular creature-feature is the effects work by Ray Harryhausen. That's two Rays for the price of one.
