Warner Bros. Pictures just released their the Smallfoot official movie trailer for their newest animated film! This is one that the girls are really going to enjoy. I got quite a few laughs in watching the Smallfoot official movie trailer and I think you will too. Smallfoot is an animated adventure for all ages, with original music and an all-star cast. “Smallfoot” turns the Bigfoot legend upside down when a bright young Yeti finds something he thought didn’t exist—a human.
