Wanna make a Jurassic Park parody called Cambrian Aquarium where it’s just the exact same plot but instead of dinosaurs it’s a bunch of marine invertebrates from the Cambrian
I want to point out that they don’t kill people. Instead you get scenes like:
“Sir, the security systems are all shutting down!”
[cut to a shot of a bunch of trilobites scuttling around on the floor]
the lights flicker and the power dies, a herd of screaming interns pelts down the hallway, fleeing the high-security wing which houses the most vicious and powerful predator of the entire age. the music swells as…
the three-foot-long shelled predator Anomalocaris flops awkwardly around the corner, wiggling its mouthparts ferociously
This sounds like a movie that very well could have been made in the 1930s.
