Inspired by NY Deputy Assistant District Attorney Eunice Hunton Carter, who worked for District Attorney Thomas E. Dewey.
The movie opens with the following prologue from Executive Producer Harry M. Popkin:
To those colored men and women of the Intelligence Service who unflinchingly risk their lives in the interests of good government this motion picture is respectfully dedicated. Their part in the American scene can not be over-estimated - nor can their courage. Their efforts have contributed to, in a large measure, towards this country, a safer and finer place to live in.
In the daily battle against organized crime these men and women have fought bravely, and have achieved more than victory. They have not only gained all the things which they sought, beaten the octopi which have tried to gain a stronghold on the American public, but have brought distinction to their own race. To these unsung heroes, these silent guardians of law and order - the "Gang Smashers of America" we give thanks, and bestow our humble praise.
On original promotional material from the movie's original production company Million Dollar Productions Nina Mae McKinney's name is spelled correctly. On material put out by reissue company Toddy Pictures Company her name is misspelled as Nina May McKinney.
On some of the original promotional material the credit "Original story by Ralph Cooper" appears.
Nina Mae McKinney sings the song "I Just Can't See It Your Way" twice. Neva Peoples sings "That's What You Gets In Harlem".
