Sarah Vowell
In 2004, Vowell provided the voice of Violet Parr, a shy teenager, in the Pixar animated film "The Incredibles", and returned to her role for the film's sequel, "Incredibles 2", in 2018. Additionally, Vowell has also lent her voice to the character for various related video games and "Disney on Ice" presentations in the years following the film's release. The makers of "The Incredibles" discovered Vowell from episode 81 – "Guns" "This American Life", where she and her father fire a homemade cannon. Pixar made a test animation for Violet using audio from that sequence, which was included on the DVD of "The Incredibles". She also wrote and was featured in a documentary included on the same DVD entitled "Vowellett - An Essay by Sarah Vowell", where she reflects on the differences between being superhero Violet and being an author of history books on the subject of assassinated presidents, and what it means to her nephew Owen. Vowell also played Fernanda, Theacher "Aunt" Deborah and Mary Kelly in "The School Future".
Michael Giacchino
In addition to his long list of soundtracks, in 2005 Giacchino collaborated with Walt Disney Imagineering in creating two new soundtracks for the updated versions of Space Mountain at Disneyland, at Disneyland Paris, and Space Mountain at Hong Kong Disneyland. Giacchino was also contracted by Sarah Vowell, who played character Violet in "The Incredibles", to compose the score to the audio version of her book "Assassination Vacation". Michael Giacchino's music can also be heard in "" during the "travel log videos" shown in the queue for both the Disneyland and Walt Disney World versions of the attraction.
