Some of this info was taken from another (now extinct) site:

The Three Musketeers: Any version of this movie will suffice, but the original version from the 70's is the most true to the book. The Disney version is fine, but doesn't stick to Dumas' plot. The Four Musketeers: (also from the 70's) is actually the second half of the novel that the 70's version of The Three Musketeers doesn't cover. Both movies were filmed all at once to save money and then split into 2 films.

Captain Blood: Starring Errol Flynn in the movie based on the equally enchanting book. No one swachbuckles like Mr. Flynn.

The Princess Bride: A little silly in parts, but no less phenomenal than any of its fans will tell you. Inigo Mantoyan is the Castillian Swordsman to the letter.

The Adventures of Baron Munchausen: I don't care if it's silly. This man has flair.

Orlando: which deals with a cross-dressing, gender switching time traveler roughly based on a Virgina Woolf novel. Some interesting settings early on of Elizabethan England in the winter, and a diplomatic scene set in a foreign land will also provide some intriguing ideas.

Lady Jane : about the brief reign of Lady Jane Grey on the throne of England for seven days. Intriguing and filled with plot ideas about a possible coup against the Queen.

Dangerous Beauty: The movie for those aspiring to be Vodacce courtesans, and the obvious best source material about Venetian prostitutes in the Renaissance (and probably the source material for the Vodacce courtesan the more I watch this movie) Go out and rent or buy this last movie. You will never regret it if you plan on setting your adventures in Vodacce or need a good picture for female players to emphasize with.

The Man in the Iron Mask : even old musketeers still got it!

Cutthroat Island: wacky adventure on the High Seas.

Plunkett & MacLeane: Plunkett (Robert Carlyle) and MacLeane (Jonny Lee Miller) terrorize London's aristocracy, netting grand hauls and seeing themselves become legends in their own lifetimes.

The Patriot: A widowed father of seven children is suddenly pulled back into the savagery of battle when his family is threatened by the American Revolution. A good revolution movie... Lots of action. Muskets and swords abound.

Mask of Zorro: So maybe El Vago isn't terribly original - I still want to play him!

Dangerous Liasons: The grandmother of all "Idle Rich" movies. The leads are certainly Montaigne nobles toying with the lives of others for fun.

Romeo and Juliet: I prefer the version from the early 70's myself.

The Musketeer: is director Peter Hyams’ new take on Alexandre Dumas’ classic tale. Newcomer Justin Chambers stars as D’Artagnan, a dashing swordsman whose courage and willful nature place him at odds with powerful forces in 17th century Paris. Legendary Hong Kong action choreographer Xin Xin Xiong designed the film’s fight sequences, mixing eastern and western styles and traditions to stunning effect.

Horatio Hornblower A&E Series: 1999 Emmy Award Winner for Outstanding Miniseries! Huddled against the biting wind of a January gale, a thin young man sits miserably in the stern of a small boat battling its way across the churning waters of Spithead Bay. It is 1793, and Horatio Hornblower is reporting to duty aboard the battleship Justinian...
The swashbuckling saga of the legendary sea-faring hero comes to life in these epic films based on C.S. Forester's classic novels. Set against the bloody backdrop of the Napoleonic wars, Hornblower charts a course for high adventure, following the raw recruit as he battles the French, evades capture, and rises through the ranks of the King's Navy.

Horatio Hornblower, The Adventure Continues: Return to the high seas with two more scintillating adventures starring Ioan Gruffudd as C. S. Forester's dashing naval hero. Crafted and helmed by the Emmy®-winning team behind the acclaimed, original series this adventure features two full-length movies based on the book Lieutenant Hornblower.
As The Mutiny opens, Hornblower is languishing in a prison cell in Kingston, Jamaica, jailed for his role in removing the deranged Capt. Sawyer from his command aboard the HMS Renown. Visited by Capt. Pellew, his former commander and mentor, Hornblower revisits the harrowing events that have brought him to face court martial and the very real possibility of a death sentence.
The saga continues in Retribution, as Hornblower reveals to the court the details of an assault on a Spanish fort that succeeded in large part because of his gallantry. Despite these heroics, Hornblower's fate remains in question--until a surprise witness removes the shadow of doubt cast across the young sailor by Captain Sawyer and his cronies.

A&E Series: The Scarlet Pimpernel Book I: Crack shot, accomplished horseman, envy of the aristocracy, foppish Sir Percy Blackeney (Richard Grant) is one of the richest men in England. He's also the reckless Scarlet Pimpernel, mastermind of daring rescues during the bloodiest days of revolutionary France. His wife, witty and beautiful Lady Marguerite (Elizabeth McGovern) will risk anything to save him from exposure and the man who may know his secret -- Percy's sinister arch rival and Marguerite's ex-lover, the French spy Chauvelin (Martin Shaw).

A&E Series: Scarlet Pimpernel Book II: Madamoiselle Guillotine : Richard Grant returns to his role as the foppish British aristocrat who leads a dangerous double life in this second SCARLET PIMPERNEL movie. At a party thrown by the Blakeneys in London, the Marquis du Rochambeau, an old friend of Marguerite's, arrives with a story of woe and a plea for help in rescuing his daughter, who is trapped-though safe-in France, with the Revolutionary authorities looking for her. The Pimpernel immediately undertakes a mercy mission, but once in France, he is nearly undone by a farmer who reveals his presence the Chauvelin, who is also looking for the Marquis' daughter. It is just the first of many deceptions, betrayals and stunning turns that complicate what at first seemed to be a rather straightforward rescue.
