The Scarlet Blade (aka The Crimson Blade) (1963)

Set in 17th century England, King Charles I (Robert Rietti) is held prisoner by the forces of the Cromwell government. A band of Royalists led by an adventurer (Jack Hedley) known as the Scarlet Blade attempt to free him. The daughter (June Thorburn) of the tyrannical head (Lionel Jeffries) of the Cromwell loyal Roundhead forces works in secret with the rebellious Royalists. Written and directed by John Gilling (PLAGUE OF THE ZOMBIES), this is a well made and enjoyable swashbuckler that doesn't quite reach its potential. Most of it is due to the casting of the puny looking Hedley, who makes for a rather wan swashbuckler. It might have been better if he had switched parts with the dashing Oliver Reed who plays the Captain in the Roundhead forces who is in love with the Colonel's daughter. Reed's obsessed with love Captain is by far the most interesting  character in the film. So in love that he's willing to switch loyalties to gain her favor, alas with tragic results. I thought she treated him rather shabbily myself. It's no ADVENTURES OF ROBIN HOOD to put it mildly but if you've a taste for this sort of thing, there's a lot here to enjoy. With Michael Ripper, Duncan Lamont and Suzan Farmer.
