No plot spoilers included**

1. Moana was deliberately designed to have a "realistic" body type.

2. The original story for the movie focused on Maui — the demigod trickster played by Dwayne Johnson — and Moana was a secondary character on a mission to rescue her love interest.

3. The filmmakers wanted voice talent involved in the film to have some connection to Pacific Islands.

4. Auditions weren't opened up for Maui. They only wanted Johnson, and reached out to him directly.

5. "Moana" is both a name and a word in the South Pacific. It means "ocean" and is not a gendered name.

6. The filmmakers saw so many roosters and pigs on their research trip to the South Pacific, that they decided they needed to include them in the movie. This is why they added Hei Hei and Pua.

7. All the noises Pua makes are real pig noises, and therefore is not voiced by a human, like many other animated animals.

8. Hei Hei's voice is an interweaving of Alan Tudyk voicing rooster sounds and real recorded rooster sounds.

9. Hundreds of women, aged between 14 and 30, auditioned for the role of Moana.

10. It's a complete coincidence that Auli'i Cravahlo looks so much like Moana. The character was designed before she was cast.

11. The animators originally envisioned Maui as being bald.

12. Animators used video of Johnson's recording sessions to help flesh out Maui's movements. Maui's dimples and eyebrow raise are directly based on Johnson's.

13. Animators and the special effects team spent a lot of time envisioning how to create the ocean as a character, so that it didn't just look like a serpent coming out of the water. The effects team created an entirely new system called Splash to allow them to animate water for the movie.

14. About 80% of Moana has special effects. For comparison, only 46% of Big Hero 6 has special effects.

15. Whenever Moana wears red, it is a nod to her royal roots.

16. A slit was included in Moana's skirt so that she could run and jump more easily.

17. Flounder, Olaf, Sven, Baymax and Flash (Zootopia) all make cameo appearances in the movie. People involved in the creation of the movie say that Olaf and Flash are very hard to spot.

18. During one of the songs, a character sings the words "a diamond in the rough". This is a reference to Aladdin.

For those of you who have seen Moana, what was your favourite song? Mine was "You're Welcome".
