This film was produced directly by Allied Artists (formerly Monogram). It was made in hopes of shedding their "poverty row" image. It was given a larger budget and shot in color and Cinemascope and ran a full reel longer than their usual 60-70 minute fare. Allied Artists was able to book it under percentage contracts rather than flat rates.
