No, it's not the LEGO Jurassic Park game. This is arguably better though. When you get the opportunity to recreate the best dinosaur film ever in stop-motion with $US100,000 of plastic blocks, are you going to decline? Of course not.
The entire movie would be quite a lot of work, so instead, Paul Hollingsworth, his daughter and "and all their friends", going by the clip's description, crafted a condensed version instead that comes in at a bit under four minutes.
Hollingsworth's special effects company, Digital Wizards, had a hand in things too, so the quality is definitely above that of your average fan reproduction.
As you can see, it was worth the effort. I feel sorry for whoever has to sort through all that LEGO so it goes back to its original owners.
