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.

As I've heard it said whenever producers invite specialists to be a part of the film it's not expected the directors or anyone will actually take them seriously at all or even ask. They being there is just so they can say they had a specialist present, whether or not they gave meaningful advice.

Lindybeige told a story in one of his videos about historical accuracy in films and people invited to the set to help film makers makes things accurate, and in the story he was telling from one such person his experience amounted to telling the film crew that a banner they were using was not an infantry standard but was a cavalry standard.

He was only there to be officially entered into the credits as an adviser to give the film some authority.
