yep.
Wasn't I supposed to?
Yes, just asking what you meant.
The moments in the clip with the Styracosaur chasing the men are also re-creations by Peter Jackson and co. That was originally in the script and very well may have been shot. I would have mentioned that, but it was already long enough!
Fun bit of trivia: to make the sounds of the Styracosaur roaring, they took Fay Wray's screams from the movie and played them slowed way down.
