Directed by Spencer Gordon Bennet, it stars George Reeves, Nelson Leigh, William Fawcett, Hugh Prosser, and Lois Hall.

In this version, the youth Galahad, trying to emulate his father Sir Lancelot, wants fervently to be admitted to the Knights of the Round Table order.

Galahad, aided by Sir Bors, is hindered in his quest by Ulric, the Saxon King, who invades England, and by Merlin the magician, who harasses our hero at every turn.

Galahad suspects that the Black Knight is a traitor within Camelot who seeks the throne in alliance with the Saxons, while Morgan le Fay, Arthur's half sister and also a magician, helps him fight both Merlin's magic and the Saxons.

Source:[3] The Adventures of Sir Galahad was based on Arthurian myth and legend, a setting that gave it "unique" opportunities for a serial.
