Eventually they also appeared on the big screen. To bring the Junior G-Men to life on the big screen, Universal Studios enlisted the Little Tough Guys and the Dead End Kids, a group of on-screen street toughs that later became known as The Bowery Boys. Two serials were made: "Junior G-Men" (1940) and "Junior G-Men of the Air" (1942). In "Junior G-Men", a 12-chapter serial, a gang of street kids work with the FBI and the Junior G-Men to find and rescue their leader's father, a scientist who has been kidnapped by "The Flaming Torches," a group of saboteurs in league with a sinister foreign power. The second film is a 12-chapter serial, "Junior G-Men of the Air", in which the Junior G-Men thwart the "Order of the Black Dragonfly," a Japanese fifth column organization planning to destroy America's oil wells. In "Let's Get Tough!" the East Side Kids call themselves "Junior G-Men" when investigating sabotage.
