Oceanic wise guys meet up with a small fish who has a big attitude in this computer-animated comedy. Don Lino (voice of Robert De Niro) is the patriarch of a family of sharks who lord over a bustling aquatic community based along a massive underwater reef. Don Lino has two sons, Frankie (voice of Michael Imperioli) and Lenny (voice of Jack Black); Frankie is a carnivorous tough guy who takes after his father, but Lenny is, at heart, a kind soul who has earned the ire of his dad by becoming a vegetarian. One of Don Lino's cronies is Sykes (voice of Martin Scorsese), who runs a "whale wash" where Oscar (voice of Will Smith) scrubs aquatic mammals for a living. Oscar is a small but ambitious fish who dreams of making something of himself, and when a dropped anchor accidentally kills Frankie, Oscar is suddenly (if mistakenly) celebrated as "the shark killer." Oscar's overnight fame attracts the attentions of Lola (voice of Angelina Jolie), a slinky dragon fish who woos Oscar away from his steady date, Angie (voice of Renée Zellweger); however, Oscar strikes up a friendship with Lenny and has to decide what to do when Don Lino and Sykes decides it's time to "take care" of the "different" shark. Also popping up in Shark Tale's all-star voice cast are Peter Falk, Vincent Pastore, Ziggy Marley, and Katie Couric.
