One of over 700 Paramount Productions, filmed between 1929 and 1949, which were sold to MCA/Universal in 1958 for television distribution, and have been owned and controlled by Universal ever since; its earliest documented telecast took place in Denver Friday 3 Juy 1959 on KBTV (Channel 9).
The play "Danger, Men Working" (upon which the film is based) was mystery writer Ellery Queen's only stage play. It was scheduled to open at Broadway's Longacre Theatre in March 1936, but producer Raymond Moore closed the play out of town after tryout runs in Baltimore and Philadelphia. The cast included Broderick Crawford and Lee J. Cobb. Instead of continuing to revise the play, it was sold to Paramount Pictures for $10,000.
