I met the linguist they consulted for the movie, and he had a funny story. Apparently at one point the main character makes a comment about being able to translate the atlantean language almost instantly as it was the common ancestor language or w.e. So the linguist read the script and told them "in language doesn't really work like that so you might want to change it." 

And they liked it how it was. Lol

Oh also that linguist basically invented Klingon for the star trek films.

Milo had trouble understanding the language for the most part, however the Atlanteans could speak perfect English AND French because of that "root language" crap. Pretty much the only part of the movie I didn't like.
