The Finest Hours (2016)
Disney movie about what is called one of the greatest rescues in the history of the coast guard. In 1952, during a storm weather, two WW2 era tankers just broke in two. One managed to send a distress signal out, but not the other, so while one got a lot of attention, all the second one got is one boat with 4 people going out to save them.
This is pretty much a very standard rescue drama. We have a main hero - awkward but likeable, his girlfriend - a strong female character in 1950-ies, they even got a sort of an antagonist of the movie - main hero's boss. Story is pretty simple, but visuals are quite amazing, so, if you like that sort of thing - you will like this, but you really won't find anything new in this film.
So, how true is it? My usual website gives a pretty extensive breakdown of facts. I think, some of those are taken from witness accounts, some from the books about that whole story. The whole movie is based on the book of the same name.
It seems that a lot of this is actually true to the real story. Just 4 people on a small boat went out and saved 32 people from the tanker that just snapped in two. They lost compass along the way, but managed to return safely. Still, some things are obviously not true. For example, while a lot about how Bernie and Miriam met is true, she didn't go to the coast guards station to plead for him. That arc is pure hollywood drama. Additionally, the tanker wasn't set aground, the crew actually steered it away from ground, so it wouldn't break up completely. Plus, it seems, the episode with life-boats os overdramatized. Still, key facts seem to be there, and that rescue really was just as daring and improbable as it was shown in the film.
