Fluke and Rudder

Fluke and Rudder are two sea lions who are set to appear in the upcoming 2016 animated film, Finding Dory. They are voiced by Idris Elba and Dominic West respectively.

Official Bio

 * "Fluke and Rudder are a pair of lazy sea lions who were rehabilitated at the Marine Life Institute. Marlin and Nemo find them snoozing on a warm—and highly coveted—rock just outside the center. These sea lions really enjoy their down time and would rather not be bothered mid nap—but their bark is far worse than their bite."

Trivia

 * There were initially three sea lions, with the third being called Gerald, before the directors decided to settle with two.
 * In the early stages of the sequel, Idris Elba and Dominic West were originally going to portray the villainous Dr. Mobster and a shark hunter Jinx respectively, but they were scrapped and changed into sea lions instead.
 * Andrew Stanton admitted that he casted Elba and West because he wanted to have a reunion between the two co-stars of The Wire.
