Fourth wall breaks in Disney movies...
One thing I've noticed about Disney's animated films since 'The Princess and the Frog' (2009) is that, Disney seems to make fun of their material even more so than their previous works.
Ever since films like 'Shrek' (2001) and even Disney's very own 'Enchanted' (2007) poked fun at this type of work, we - as audiences - knew that going in. It was actually their selling-point and what made their films what it is.
In 'The Princess and the Frog' (2009) which is inspired by The Frog Prince tale, the said tale appears as an actual story within the film. That's like if Tony Stark (Iron Man) handed Peter Parker (Spider-Man) a Spider-Man comic book in 'Captain America: Civil War' (2016) and said "This reflects your life! Be like him!".
With 'Tangled' (2010), Flynn Rider (or "Eugene Fitzherbert") acknowledges that people sing, no other Disney character has ever noticed this. The very fact that he is aware that characters sing to express their feelings is a bit of a fourth-wall-break.
In 'Frozen' (2013) there are many jabs at the romantic side of these films. When Anna and Hans announce their abrupt engagement, Elsa scolds them and tells Anna that she "can't marry a man she just met". Not sure if the writers knew that this line would be that remembered, but it did feel like a subtle jab at previous Disney characters who did such a thing.
Now, we have 'Moana', where Maui - voiced by "The Rock" - looks at Moana and tells her that she "wears a dress, and has pets for companions... you are a princess!". It's almost like Maui knows about the Disney store, and knows about the Disney Princess franchise and merchandise.
In a way, it's nice to see that Disney is acknowledging that their old formula isn't as fresh as what it used to be... but there are times where their adaptations of these famous stories can feel like parodies. I remember when I saw the first trailer for 'Tangled' (2010) and thought that it was a parody of the Rapunzel fairy-tale. But, in a way, the humorous tone kinda worked for that story... so it's a win-win, I guess...
