Nothing Venture

Okay, but overly long Hardy Boys type adventure mystery. This is the earliest film of this nature that I've come across.

The last of three films starring The Artemus Boys. A young brotherly trio battling crime. The film is rather poorly made and the boys was never seen on the silver screen again after this, but for the time it does provide a sense of adventure. Mainly because these types of kids movies weren't exactly a normal thing back then.
