WHATEVER THE REASON FOR NOT USING A REAL WOLF IN A FILM SCENE IS, WE ACCEPT IT HAPPENS FROM TIME TO TIME. WE CAN ALSO ACCEPT THAT EVERY SHOT IS NOT ACHIEVABLE WITH A REAL WOLF. THIS CAN BE BECAUSE THE PRODUCTION BUDGET DOES NOT STRETCH FAR ENOUGH, OR MAYBE THE LOCATION IS TOO DIFFICULT TO GET A REAL WOLF INTO, OR PERHAPS THE ACTOR IS AFRAID OF WOLVES.
