In what animated film did Martin Scorsese voice a pufferfish called Sykes?

Martin Charles Scorsese ( born November 17, 1942 ) voiced Sykes, a loan shark pufferfish in the film 'Shark Tale' a 2004 American computer-animated comedy film produced by DreamWorks Animation and distributed by DreamWorks Pictures.

The plot concerns Oscar (voice of Will Smith) who is a little fish who dreams of fame and fortune. When his blowfish boss, Sykes (voice of Martin Scorsese), says he needs the $5,000 Oscar owes him, pretty receptionist Angie (voice of Renee Zellweger) gives him her family heirloom pearl, which Oscar sells, but then loses the money gambling. Sykes' Rasta-jellyfish henchmen (voices of Doug E. Doug and Ziggy Marley) take Oscar out to rough him up, but a mix-up occurs in which Sykes' henchmen believe that Oscar has killed a shark, and the little fish returns home to be the celebrated as 'the Shark Slayer.' Oscar enjoys the high life until the sharks come searching for him. Meanwhile, shark Lenny (voice of Jack Black) runs away from home because he can't be a predator like his pop (voice of Robert De Niro) and the other sharks. Lenny teams up with Oscar. They decide to stage a fight in which Oscar will pretend to kill Lenny, then the sharks will be too scared to come after Oscar, and Lenny can start a new life. But it's not a very good plan, as Lenny and Oscar soon find out.

It was nominated for Best Animated Feature at the 77th Academy Awards, but lost to Pixar's 'The Incredibles'.
