Jurassic Park (1993)
- Before it opens up its frill, you can see nothing on the animal's neck that would suggest is has a frill. It simply appears from one shot to the next.
- As the animal opens up its frill, you can see the wire that held the frill down being quickly pulled back. You can also notice a curiously narrow area around the neck - that's where the wire was wrapped around it in the beginning of the shot.
- When the frill is fully opened, it flops around a lot. In the next shot, it is resting firmly on the animal's neck, suggesting it is either another prop, or has been attached more firmly between takes.
