The documentary “Dealt,” about one of the world’s greatest card magicians, a Texan named Richard Turner, contains no gunshots, explosions or, for that matter, violence of any kind. But it never fails to fascinate, mesmerize and inspire. If there’s a “super-hero” character in this movie, it’s Turner, who practices card moves — false shuffles, false cuts, bottom dealing — for 16 hours a day. (He spends all his waking hours with a deck of cards in his hands). Filmed in part at the Magic Castle, in Hollywood, and at various performances around the country, “Dealt” introduces viewers to a level of craftsmanship, discipline and hard-earned expertise that few humans ever encounter.
