Fluke and Rudder are sea lions in the Pixar film Finding Dory. A running gag is when Gerald comes up on their rock, both of them bark, "Off! Off! Off!" at him.
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.
Fluke and Rudder's recurring lines: "Off! Off! Off!" when shooing away Gerald is similar to the Seagulls cawing, "Mine! Mine! Mine!" in Finding Nemo.
Fluke and Rudder's tags are labelled A1 and 13 respectively, which together becomes A113, a recurring joke in Pixar films.
