For some filmmakers, the idea of working with children and animals -- not to mention the entire family film genre, for that matter -- is an abhorrent proposition. But 'Dolphin Tale' director Charlies Martin Smith says he learned from the best -- from the likes of George Lucas and Carroll Ballard. Thanks to those influences and Smith's familiarity with animal-centered stories (he directed Disney's franchise-setting 'Air Bud'), 'Dolphin Tale' is one of the rare live-action PG films to score rare reviews.
