A little late on this but I always enjoyed, "The Flame & The Arrow" (1950) with Burt Lancaster. It's been referred to by some as "Robin Hood in Italy", but I love it just the same! Plus, Burt does many of his own stunts, as he had once been an acrobat.
Same with "The Crimson Pirate" (1952).
For a good mix of comedy and swashbuckling, I recommend Danny Kaye's, "The Court Jester", one of the funniest movies ever!
