The score was written by Rudy Schrager, an immensely talented composer who's been all but forgotten. (His Gunsmoke (1955) scores are required listening for any movie music fan.) When, after WWII, the union representing film composers prohibited them from writing TV music, Schrager and several other composers had some of their film scores re-orchestrated and recorded in Europe. Schrager, et al, could then be paid for their work when this "laundered" music was used in TV shows - one of which was Adventures of Superman (1952).
To get a superior quality copy of this U.S. production, the UCLA Film and Television Archives acquired a print of the British release. This version does not contain the Monogram logo and has "Pathe Presents" above the main title.
Johnny's illness ('spells') is due to a close explosion of an artillery shell during the Battle of the Bulge in Europe. It was referred to as shell shock in WWI and combat fatigue in WWII. It has since been termed post traumatic stress disorder (PTSD). The sight of a physician making a house call seems unusual nowadays, but was a common practice at the time.
The two male leads are named (Johnny) Dixon and (Mike) Carr, an obvious hat-tip to Cornell Woolrich's fellow mystery writer John Dickson Carr.
This film was restored and preserved by the UCLA Film and Television Archive with funding provided by the Film Noir Foundation.
