Unused JURASSIC PARK 4 Concept Art by Carlos Haute

Here's concept art for the half-man\half-dinosaur creatures of Jurassic Park 4. This is kind of an old set of concept art, but it's fun to look at.

The sequel itself has been in "Development Hell" for years, but yesterday producer Frank Marshall tweeted that the film is still on track.

All's well on JP4, updates soon.

So, there's no telling what could happen with that film. But we do know the script by John Sayles was scrapped. Accroding to Jurassic Park Wikia "Sayles's story was about a new character, Nick Harris, who returns to Isla Nublar, and retrieves Dennis Nedry's can with dinosaur embryo's. He is captured by the Grendel corporation, which now owns InGen, and he is hired to train five creatures that could be called 'di-hu-ogs'. These creatures are born from a mix of DNA from dinosaurs, humans and dogs. They are created to carry guns and would be used as mercenaries."

Whether this is legitimate concept art or not is hard to say. According to Screenrant ILM denies that the artwork was done by them. It definitely looks a like Huante's work.
