Just William's Luck is a cheaply made B feature from 1948 featuring Richmal Crompton mischievous hero. It holds up remarkably well. Maybe because the nauseating Violet Elizabeth is kept to the minimum.
William (William Graham) is introduced as the archetypal menace. By the time he gets down for breakfast, he has swapped boot polish for his father's shaving foam and vice versa.
He interferes in his older brother's life. Wondering why he has not married yet and tries to fix him up with film star Gloria Gaye (Hy Hazell) who has come to town for a short break.
William and his gang, the knights of the round table decide to scare someone in a haunted house.
Unbeknownst to them some fur coat thieves plan to rob it. Can Just William save the day.
This is a brisk effort, the finale with the thieves is directed like a silent movie. Silly and fun even for children of today.
