The show features Roger Moore in his first starring role, as Sir Wilfred of Ivanhoe, in a series of adventures aimed at a children's audience.
In his absence, power had been taken by his younger brother, the ambitious and wicked Prince John, who sought to strip the people of their rights and land.
The dashing and heroic knight Ivanhoe, with his father-and-son companions Gurth and Bart whom he had freed from servitude (from the evil Sir Maurice), attempted to right wrongs, secure justice, help those in need, and thwart John and his allies.
In December 1956, Columbia Pictures signed up Roger Moore, then working with limited success in Hollywood, to play the title role in an intended series for transmission in both America and the UK.
Moore insisted on undertaking much of the stunt work himself, resulting in several injuries including three cracked ribs from a fight scene and being knocked unconscious when a battleaxe hit his helmeted skull.
