Violet Parr
Vowell stars in a documentary about her work in the film, "Vowellet: An Essay by Sarah Vowell", which is included as a bonus feature on "The Incredibles"' 2004 DVD release. In the "video essay", Vowell discusses the various differences between voicing a superhero and becoming an action figure while she was writing about presidential assassinations, contrasting the two distinct careers. The animators also animated Violet to some of Vowell's dialogue from the documentary. Bird, who voices costume designer Edna Mode, was the only other actor Vowell recorded with while working on both films. The director would sometimes temporarily provide the voices of other characters for Vowell to act opposite of, such as Elastigirl in lieu of actress Holly Hunter. For "Incredibles 2", Vowell had not been allowed to read to entire script while recording her dialogue, having only been allowed to preview small excerpts in which Violet is speaking or having conversations with other characters. Until watching the film for the first time, Vowell had been under the impression that "Incredibles 2" would mostly be about Violet's anger at her father until experiencing the film's other storylines and characters. Despite 14 years separating the releases of the first and second films, Vowell did not find resuming the role to be difficult, identifying Violet as a character to whom she feels "closely tied", having played her for approximately one-third of her life. Syfy Wire's Heather Mason observed that Vowell shares her dry sense of humor with Violet. To-date, the "Incredibles" films remain Vowell's only animated film roles.
