PIRANHA 3: CONTRACT ON FULTON (1995)

Bruce Dern(Vito), Antony Hopkins(mayor), James Belushi(Det. Flipper),
Burt Young (Joey the Cheese) 

 The dread flesh-eating flying fish are back! Manhattan mobsters unleash
 the beasties upon the city's zealous mayor, who's vowed to smash mob
 control of the fish market. Bruce Dern, in a paraphrase of his role in
 INCREDIBLE TWO-HEADED TRANSPLANT, is the Mafia's smack-snorting mad marine
 biologist. With Anthony Hopkins as the mayor, James Belushi as Detective
 Flipper, and Burt Young as Joey the Cheese.
