At one point in the film, the gang (Bobby Jordan, Leo Gorcey, Ernest Morrison and others) are passengers in an old open phaeton (a four-door convertible) that is driving up to an airplane on the parking ramp. The driver is going a bit too fast and cuts the wheel too sharply, and the car flips over on its side. That was really an accident, not a stunt, as the scene is shot in one continuous take, and you can clearly see Gorcey's, Morrison's and Jordan's eyes widen and a terrified look on their faces as the car begins to tip over.
This film's earliest documented telecast took place in Los Angeles on 3/12/50 on KNBH (Channel 4).
Racial joke: Following a fight, Muggs, being Caucasian, gets a black eye while Scruno, being negro, gets a white eye.
Sunshine Sammy Morrison and Donald Haines were not originally part of the East Side Kids, but both had been prominent with Our Gang. Morrison was the anchor of the first Our Gang cast, and Haines was an early tough guy.
The film was released just several months before the US entry into WWII. The theme of wartime espionage and sabotage became extremely timely.
