But the animal took an instant dislike to him - and the actor is convinced the horse's earlier movie roles have left it "stuck up".
Sam Worthington tells British magazine Nuts, "I hate that f**king horse! I couldn't get near the f**king thing without it biting me. It has an attitude problem!
"I wanted to punch it in the head the first time I met it. Just because it's done more films than me - such as Alexander and Prince of Persia - it thinks it's hot s**t. It's so stuck up, it never leaves its trailer!"
