Well, why stop there? You must include your very own William Shakespeare. He certainly changed around his historicals. Only, he didn't really write them did he? Christopher Marlowe did...only Marlowe was actually someone else, too.

Gee, who
was there for the facts?
There's also a replica of the Globe Theatre in London, only it's not really a replica, as no one knows what the actual Globe Theatre looked like, to make a replica.

I've actually been to it. paid the price of the tour too, knowing it wasn't real.
The fact is, no one was around during most of history, to sit there and write verbatim whole, private dialogues of conversations, or even much of the events.
Do we really know what Marc Antony & Cleopatra felt for each other?
What did Henry V really say to his fellow officers the night before the battle at Agincourt?
I don't think
Braveheart ever represented itself to be a factual documentary or representation of events any more than
Hamlet or
Macbeth.
Troy was made into a film too. There's quite debatable evidence that it actually existed.
How do we really know what a
Gladiator felt, to make that film?
A lot of films could be attacked for accuracy. I think of films as fiction & entertainment unless told otherwise.
