1) 6-foot-4 stuntman Glenn Ennis was one of the two stuntmen who stood in for the computer generated bear while filming was taking place and was charged with portraying as a convincing Grizzly as possible. He states, "In rehearsals, I would wear a blue suit with a bear head which obviously doesn't make it into the film as the CGI guys paint the bear in. Director Alejandro G. Inarritu was adamant that the blue bear move just like a real bear would move and it was essential that it had the same nuances that a bear would have. Even though it was a big Smurf bear, it still had to be as authentic as possible." The 51 year old Vancouverite explained that the role often required him to spend quite a bit of time up-close and personal with the film's star DiCaprio. He goes on to say, "If you notice the bear's head in the picture, they wanted the bear's mouth to be right on his lower back. I was supposed to grab his jacket with my hand to make it look like the bear's jaws we're pulling it in order to have the bear's jaw in the small of his back. Basically, my face was in his butt. My face was in Leo's butt for a fair bit of time. I can see how that's someone's fantasy, but it wasn't mine."
