William, the obstreperous Welsh schoolboy created by children's novelist Richmal Compton, appeared in several film incarnations in the 1930s and 1940s, none of them as successful as Compton's original books or the spin-off radio series. William Graham stars as the argumentative title character, who gets off to a bad start in the first scene by stealing his sister's cosmetics and wooden Indians -- after mixing up the shoe polish with the shaving cream. Venturing outside to play with his schoolmates, William decides to become a junior-league "righter of wrongs" by forming the Knights of the Square Table. This leads them to a "haunted" house, where William makes up for his past misdeeds by corralling a gang of crooks. Just William's Luck adheres strictly to formula, pleasing fans of the Compton books but doing nothing to broaden the character's appeal.
