Esape from Jurassic Park: Trailer released
There were plans for an animated series based on Jurassic Park pitched, and even got a trailer made. But Spielberg, growing numb to the sheer amount of merch of the film, refused to see it. presumably why it was shelved. For years since, there was only a few pieces concept art (including by Wiliam Stout) and the pitch bible to go off of. As for the latter itself, not too much of the story this would have had of the park reopening and Biosyn opening their own. But not anymore! It's been posted to the public at last! What a lovely halloween treat!
