During the Hollywood run, MGM purchased the rights to the play for $20,000 and later paid an additional $15,000 for the rights to the Broadway production.
The play originally opened in a small theater in Hollywood, California, USA in late September 1942, with the title "Cry Havoc". It opened on Broadway in New York City, New York, USA on 25 December 1942 with the title "Proof Through the Night", but changed the title back to "Cry Havoc" on 30 December 1942, probably because of bad notices. However, it closed on 2 January 1943 after only 11 performances. The opening night cast included Carol Channing and Ann Shoemaker.
