Koosh, I didn't add Offscreen Killer, as that is for a particular type of cliche that doesn't seem to apply here. I have added "Monster" though . This is another film I haven't seen (or indeed even heard of), so I bow to your eclectic DVD collection!
Good point. Especially since the Paleosaurus has already been seen by this point, and I even say we see it (through Sampson's binoculars) so it isn't offscreen at all. And I did miss 'Monster,' so thanks for adding that.
