The Tucson zoo has a dinosaur exhibit I filmed as a 'trip to the past,.' These are life-size loving realistic replicas tucked in the trees and bushes. I mixed in some modern footage of a vulture, a bird slamming a mouse on a rock and other 'out of time' looking happenings to make this look like a back in time film. I had fun and this topic interests me since my books 9-10-11 take place as sci-fi back in the ice age.
