I just had a thought about Boromir while looking at a list of the ruling Kings and Queens of Scotland on Wikipedia.... and I'll get to it later in the post.
Now, I'd just like to comment on Boromir's character... as the above posts do..
Boromir was the most privileged man in Gondor. He had the best training in arms, politics, finances, history, rhetoric, diplomacy, etc. Gondor was the most advanced nation in the world... and thus you could conclude that he (and his younger brother, Faramir) were the most educated, the most learned, the most prepared men in the world to take a stand against Sauron.
Samwise was a gardener from Hobbiton. He was the most unprepared person to defy Sauron the Great.
Boromir and Sam are juxtaposed by Tolkien. Boromir should have been (perhaps more than Aragorn), the one person to be Frodo's guardian all the way to Mount Doom, but he failed in the first third of the story. The daily mundane tasks.... the lack of head bashing... and the waiting, the waiting and more waiting drove him to renounce his vow. On the other hand, gardening taught Sam patience. He could plod for months on end. He did not mind small tasks. He did not need adoring crowds.
Poor Boromir.
As for the movie, Boromir's redemption was very well done. I applaud Jackson and his team.
Now... to the Kings and Queens of Scotland. The Stewarts/Stuarts were the longest reigning dynasty of Scotland.
When Faramir interrogates Frodo, he reveals a bit about Boromir's childhood.
The Two Towers, Book Four, The Window on the West....
'And this I remember of Boromir as a boy, when we together learned the tale of our sires and the history of our city, that always it displeased him that his father was not the king. "How many hundreds of years needs it to make a steward a king, if the king returns not?" he asked. "Few years, maybe, in other places of less royalty," my father answered. "In Gondor ten thousand years would not suffice." Alas! poor Boromir. Does that not tell you something of him?'
Since Tolkien's works are to be a mythology of England, was this a direct shot at the Stewarts/Stuarts of Scotland?
The Balliol-Bruce feud was over and Scotland needed a leader to defend against the English (Edward III and the Black Prince) and to keep good relations with France (Charles V). Robert Stewart, seventh High Steward of Scotland, became Robert II, King of Scotland. The Stewarts later came to rule England as well.
Boromir is portrayed more like the Rohirrim... proud, strong, and uncultured... rather than a Numenorean like Elendil, Isildur, Denethor, Faramir, and Elessar Telcontar... noble in spirit, wise, and seeking justice.
Scotland = Rohan... wild and beautiful.
England = Numenor... dignified and judicious.
Or is it merely coincidence?
