Trivia: Kristen Bell stated that with this film, she has fulfilled a lifelong dream of voicing an animated character ever since she saw La sirenita (1989) and Aladdin (1992) as a kid. When she was around that same age, she recorded a voice box where she sang a couple of songs from The Little Mermaid, including "Part of Your World". Her Little Mermaid vocal tracks were part of the reason why she got the part of Anna, as director Jennifer Lee said to her that if she hadn't recorded her own vocal tracks from Mermaid, it would've been very difficult to the find the right one to play Anna.
