This is a live-action demonstration of the realistic dinosaur costumes created by On-Art Corporation in Japan. I think it was part of a rehearsal for a stage show or something. I liked the part where the dinosaur had the guy's head in its mouth, that seems like something a dinosaur would do. They just need to work on their blood and gore effects, because there weren't any. If I'm going to watch a realistic dinosaur stage show I expect the first five rows to get sprayed with blood and flesh like pieces of watermelon at a Gallagher stand-up show.
Keep going for the video.
Thanks to Pyrat Hero, who wants to be the hero of the show that unites humanity and dinosaurs, and everyone lives happily ever after.
