You think you know Dory? Just because she starred in Finding Nemo, and now stars in Finding Dory, doesn’t mean you know everything about her and her friends. Sure, you know she’s a blue tang (Paracanthurus) with memory problems. But there’s an ocean’s worth of trivia about Finding Dory you don’t know.

The Basics

When we catch up with Dory in Finding Dory (voice of Ellen DeGeneres), she’s living happily in the reef with Marlin (voice of Albert Brooks) and Nemo (voice of Hayden Rolence). When Dory suddenly remembers that she has a family out there who may be looking for her, they take off on an adventure across the ocean to California’s prestigious Marine Life Institute, a rehabilitation center and aquarium. In an effort to find her mom (voice of Diane Keaton) and dad (voice of Eugene Levy), Dory enlists the help of three of the MLI’s residents: Hank (voice of Ed O’Neill), a cantankerous octopus who frequently gives employees the slip; Bailey (voice of Ty Burrell), a beluga whale who is convinced his biological sonar skills are on the fritz; and Destiny (voice of Kaitlin Olson), a nearsighted whale shark.

Character Trivia

Even though Dory was already designed for Finding Nemo, filmmakers had to bring her design into current technology to use it. To achieve the specific shapes and expressions that fans would recognize as Dory, artists put images from the first movie side by side with images in production to ensure all was as it should be.

Alexander Gould, who originally voiced Nemo in 2003’s Finding Nemo will be 22 in May, so filmmakers had to recast the character, calling on 12-year-old Hayden Rolence to voice the junior clownfish in Finding Dory.

Gould, who wowed filmmakers 13 years ago, can be heard in the new movie as the voice of a truck driver.

Rolence, who was cast long before recording began, was advised that he couldn’t tell anyone about the role. That proved tough for the youngster, who wanted more than anything to share the news with his grandma.

Comedian Albert Brooks returns to the big screen as the voice of clownfish Marlin in Finding Dory. Filmmakers say Brooks is all about improv, infusing his iconic comedy into the character. While Marlin carried a big emotional load in Finding Nemo, he’s been freed up in Finding Dory, allowing Brooks a lot more improvisational leeway this time.

When designers were working on Hank, the octopus in Finding Dory, they created tapered tentacles for the cephalopod. The tentacles were modeled separately from the body, but when they tried to attach them, only seven would fit. Filmmakers later decided that it made sense that Hank would have an affliction, so they worked it into the script.

Designers gave Hank 50 suckers per arm for a total of 350 suckers.

When filmmakers cast the voices of the lounging sea lions Fluke and Rudder, they decided to bring two actors from The Wire together again, tapping Idris Elba and Dominic West.

Destiny is a whale shark who is being cared for at the Marine Life Institute, but filmmakers weren’t initially sure what ailed her. It was Bailey, Destiny’s beluga whale neighbor, who opened their eyes—so to speak. Belugas are known for their echolocation skills—a biological sonar of sorts—that is described at the MLI as “The World’s Most Powerful Pair of Eye Glasses.” Filmmakers decided that if Bailey had an enhanced sense of sight, perhaps Destiny’s was compromised. A nearsighted whale shark was born.

Destiny actually taught Dory to speak whale. Of course, the fact that Destiny is a whale shark—not a whale—explains Dory’s limited understanding of the language.

Becky, an offbeat, kooky loon who takes a liking to Marlin, is named after production manger Becky Neiman-Cobb, who insists there’s no resemblance.
