There was a scene where the Velociraptors
come into the kitchen and are chasing
the children around, and Steven wanted
the raptors to come in and stick out a tongue, like a lizard
or a snake would do, and I said, "We know for sure
that dinosaurs did not do that," and so we decided the raptor
looks through the window, and it snorts,
and it fogs up the window, and only a warm-blooded
animal can do that
