The Scarlet Blade (released in the United States as The Crimson Blade, but with the dialogue unchanged) is a 1963 British adventure film written and directed by John Gilling and starring Lionel Jeffries, Oliver Reed, Jack Hedley and June Thorburn.

[1] It is a period drama set during the English Civil War,[2] a genre not usually approached by Hammer films of that time.

[5] The Radio Times noted that Oliver Reed was "on form as a renegade swordsman with an eye for the ladies" but gave the overall film two stars out of five.

[6] A very mixed review focusing on the cast, stated, "The main problem is Hadley, who is as far as possible from the Errol Flynn type you would expect to find.

Over his career, he was much more of a world-weary supporting actor type – Hadley may be best known as the burned-out detective at the center of Lucio Fulci’s notorious giallo film, The New York Ripper.
