Ponyo on the Cliff by the Sea/Trivia
- Hey, It's That Voice!: A lot of A-Listers are in the English dub. It is Disney, after all, so they can afford it.
- In the Disney dub, Liam Neeson plays Ponyo's father, a wizard/god type person with a missing daughter that he tries to prevent from falling in love.)
- Noah Cyrus and Frankie Jonas lead.
- To be fair, the fact that the leads are a Cyrus and a Jonas relative is never played up; Disney presumably just used them because they were cute kids upon whom Disney held the contracts.
- Tina Fey plays Sosuke's mom. Matt Damon plays his dad.
- Cate Blanchett plays a tall, beautiful woman with legendary power.
- Lily Tomlin, Betty White, and Cloris Leachman play old people.
- Carlos Alazraqui (Rocko, Mr. Crocker, the Taco Bell chihuahua) plays one of the crewmembers of the ship Sosuke's dad is on.
- Rumi Hiiragi, who voices Chihiro in Spirited Away, plays a young mother on a boat.
- While she has a very minor role, Colleen O'Shaughnessey - AKA Sora and Yoshino from Digimon (Adventure and Data Squad, respectively) - is also in this movie.
