The real Purple Gang was made up of mostly Jewish members. The script of this film gave the members non-Jewish names.
The ubiquitous theme song, "Runnin' Wild" was written in 1922 and featured in a host of movies. A memorable rendition was in another 1959 release, "Some Like It Hot" performed by Marilyn Monroe with a ukulele accompaniment.
The "Purple Gang" is in the lyrics of Jailhouse Rock written by Jerry Leiber and Mike Stoller, performed by Elvis Presley.
In the file of Robert Blake's character, "Honeyboy", it shows his height as 5' 10", but Blake is actually only 5' 4".
Final film of Suzanne Ridgway and Kathleen Lockhart.
