Jurassic Park 4 is going to be a reality. And the story of its development is going to be worthy of a book some day.
Currently, a new script is being written, but there was a time when a script by John Sayles was being kicked around. His vision took things into drastic new territory involving dinosaurs equipped with weapons and human-dino hybrids.
Needless to say, this script was dismissed after rightfully being trashed on Ain't It Cool News. Badass Digest culled - from Reddit - a slew of concept art that is based on Sayles' Jurassic Park 4. The fact that the script got so far in development as to having concept art commissioned hurts my soul a little bit. Not that that art - by Carlos Huante - is terrible, it's that the idea is just ridiculous within the confines of the Jurassic Park universe. I've pulled some of my favorite pieces of art within.
They remind me of something Kevin Eastman (of Teenage Mutant Ninja Turtles) illustrated for me at a convention in the late '80s. He was tinkering around with a comic book called "DinoCommandos" or something like that...
