If I'm making a movie, and I have a vision for how something goes down, I'm not going to throw that all out the window because it didn't line up to exactly how it went down to a time nobody living today was a part of. Again, verisimilitude. You stay true to the world you make. It's the director's ultimate vision in the end. Whether it works or not will have to do to its truth in the film itself.
The first Jurassic Park has many inaccuracies on dinosaurs. One is completely made but in name only. But in the end it doesn't matter, because they are real to the world of the movie. That never ages.
Gladiator gets lots of historical facts wrong. You know Commodus was a guy who actually existed who was nothing like Joaquin Phoenix, other than being an a-hole. But in the end it doesn't matter, because all that is real to the world of the movie.
Comic book movies change things all the time from their source material. Some work. Some don't. But in the end it doesn't matter, because if it is real to the world of the movie, that's what determines if it ultimately works or not.
