To my eye it looks like the crew is in the process of furling sail in the first picture; in the others the sails are in a neat, "harbor stow."
I have mixed emotions about the three Bounty movies. The first one (actually there was an earlier, silent one in the 1920s) is generally regarded as a classic. It does indeed follow the Nordoff and Hall novels pretty closely (exception: Bligh did not command the Pandora - and the books didn't say he did). All the critics praise Charles Laughton's and Clark Gable's performances; to me they come across as caricatures, but that's just me. The Marlon Brando/Trevor Howard version is, in terms of historical accuracy, the worst - though there's some beautiful photography in it. Brando just isn't right as Fletcher Christian. (The real Christian wasn't an officer; he was a master's mate - and the notion that he was an aristocrat is ridiculous.)
The DVD version of the 1960 movie includes, as a "special feature," a short, black-and-white documentary about the building of the ship - and the long voyage she made from Nova Scotia to Tahiti (with herds of visitors coming on board at every stop along the way).
The most recent movie, with Anthony Hopkins and Mel Gibson, has a lot to recommend it. For one thing, it's the only one that depicts Bligh as a young man (he was 34 at the time of the mutiny). And it makes the story a small-scale, intimate, human one, rather than a wide-screen epic. It's based on a good book by the historian Richard Hough, called Captain Bligh and Mr. Christian. Let's see if the following gets past the electronic censors. Hough offered the controversial interpretation that one big reason for the mutiny had to do with an "improper relationship" between Bligh and Christian. The movie hints at that - if you know what to look for.
My biggest gripe with that movie concerns the script. The writer, Robert Bolt, was a fine playwright (think: "A Man For All Seasons"), but he made no effort whatever to find out what sorts of things the characters in the Bounty story might have actually said. He didn't understand the ship's command structure (Bligh did not demote Fryer and "replace" him with Christian), and apparently made no effort to get acquainted with the nautical idiom. (No seaman would ever tell somebody to "get on the boat." "On board the boat," or "aboard the boat," or even "in the boat," ok. But one of the first things one learns about sailor-speak is that nothing ever happens on a ship or boat.)
The Nordoff and Hall trilogy is wonderful. The three books are titled Mutiny on [betcha the publishers picked the title] the Bounty, Men Against the Sea, and Pitcairn's Island. Essential reading for any ship lover.
I think Cap'n Mac is right about the replica's rig. Some ships did have permanently fixed royal yards by 1787, but not many. And the Bounty wasn't one of them. There's a notation in Bligh's log to the effect that the original lower studding sails were "to long, so I cut them and made a royal out of the canvas." On my model I put a royal on the main mast, but none on the fore or mizzen.
