How does a human fit inside a raptor? The standard way would probably be as bite-sized chunks, but if you’re Stan Winston and the effects team behind Jurassic Park, you’d want the human being to be in one piece.

This amazing behind-the-scenes video takes the raptor from a “garbage bag” test in foam to the terrifying final product. The actor inside the suit, John Rosengrant narrates and explains the process (as well as the challenges). The video is part of a larger blog post from the Stan Winston School which features even more information and still photos, but the video itself is remarkable (if only to watch a raptor ripping up a towel in front of The Terminator).

There’s no doubt that this movie had a profound impact on audiences, and that scene in the kitchen is one of the keystones that made raptors a household name more frightening than T-Rex. It’s priceless to be able to see the ingredients that went into it, partially because seeing how the trick was done only manages to make the magic more impressive. More like this, please.
