Edna Mode [SEP] Creation and voice
Bird's colleagues had to heavily convince him to voice the character himself. Finally succumbing to "popular demand" from his fellow Pixar employees, Bird joked that he was ultimately cast as Edna simply because he was both affordable and available at the time. A similar tactic was used for several other supporting characters in the film: animator Bret Parker voices Kari, the Parr family's babysitter, writer Bud Luckey voices government agent Rick Dicker, and production designer Lou Romano voices Bernie Kropp, Dash's teacher. Bird described Edna's voice as a combination of a Japanese and German accent, deciding to draw influence from these countries because "they're two small countries that have amazing design and amazing technology", citing cameras and cars as examples of technology in which they specialize.
