That's the trouble with most movies - they are movies, with actors, and make believe sets. They are not the real thing.
.
As an "interested outsider," as well a "small potatoes" film maker, whether you are simply a still photographer, or a movie maker - when you must "sell it," when you make it for the "commercial market," you wind up doing things you might not otherwise do, compared to just making it for yourself.
.
Bottom line, from a purely commercial point of view, the film can not lose money - not matter how authentic it might be.
.
The aspect about this particular subject, the Indy, is not that it was one of President Roosevelt's favorite ships or that he was a passenger and rode it to South America; it was not really about how many people died; but there were so many highly unusual aspects about the events leading up to the disaster, during the disaster, after the sinking, and well after the disaster was long gone. It still is not gone.
.
They really don't need to "make up" a whole lot to provide the audiences with interesting facts and bylines.
.
It terms of the purely rare and unusual events about the entire Indy story, certainly the interests and pursuit of justice on the part of Hunter Scott's involvement is as worthy as any other particular part, not from a moral or patriotic, or "life or death" standpoint but, simply, as an interesting, unusual, and intricate part of the overall story.
.
Likewise, what Captain Mc Vay's son, Charles (not a central character in the events), what he has had to say is, I believe, very important as well. I just wish we knew what Mrs Mc Vay had to say.
.
I personally know a crew member of the Indy, who left the ship several months before the sinking. He left it for pilot training, flying the amazing Corsair thru war's end.
.
Like Captain Mc Vay's son, he refused to entertain for even a second that the Navy lied to Captain Mc Vay about the presence or not of enemy ships.

It was impossible for him to even "consider" the possibility that our Navy and government would lie about receiving the Indy's distress messages. It was like telling him the world was square.
.
That is also one of the many incredible aspects of the Indy's story, not just all the lies and coverups, but the Navy would turn around and court martial Captain Mc Vay and lynch him as the tragedy's scapegoat.

Blaming, then convicting Mc Vay for the lost lives is close to being one of the most unconscionable and despicable acts U.S. acts in this country's entire history.
.
At 90+, my friend still feels guilty about "leaving" his shipmates.
.
Though he bought three different books on the "Indy," he starts them but can't read them.
.
He will not watch any video about the tradegy or the survivors, and does not want to see any still pictures, either. The whole thing is too painful for him.
.
I think all sides of the story need to be represented, even those side which ostensibly appear either "remote" or not central to what indeed happened to the very real people who died and those who suffered.
