<Snipped quote by Doivid>
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.
That's depressing and hilarious. "look we consulted actual experts!!!"
He decided in his headcanon that it was OK because the character Milo only 'thought' that was the reason and was actually mistaken (eg unreliable narrator I guess), so it made them leaving that in the script OK.
