Otto Preminger had directed and starred as Baumer in the
Broadway production of Claire Booth Luce's play, which opened on November 3, 1939, at the
Plymouth Theatre, where it ran for 264 performances, and he reprised the role for a national tour in the summer of 1940. According to the
New York Times,
20th Century Fox purchased the screen rights for $25,000 in the spring of 1941 but temporarily shelved the property because studio executives felt Boothe's "statement of the opposition between fascism and democracy had become self-evident to the point of banality." In April 1942,
William Goetz, serving as interim studio head while
Darryl F. Zanuck was fulfilling his military duty,
greenlighted the project and assigned it to director
Ernst Lubitsch. Originally Austrian actor
Rudolf Forster was cast as Baumer but he returned to Germany leaving a note "I'm leaving to join Adolf (Hitler)". Goetz wanted Preminger to reprise the role, but Preminger insisted he wanted to direct as well. When Goetz refused, Preminger offered to direct for free and agreed to withdraw from helming the film but remain as Baumer if Goetz was unhappy with his work at the end of the first week of filming, and Goetz agreed. Preminger thought the screenplay by
Lillie Hayward was "awful" and hired newcomer
Samuel Fuller, on leave from the
United States Army, to help him revise the script. The men agreed Luce's original play, written as a call to arms, had to become a morale booster for a country firmly entrenched in
World War II. As such, they presented the story as a
flashback to the period prior to America's entry in the war. Principal photography began on September 28, 1942, and at the end of the first week, Goetz told the director he was so pleased with the
dailies he was offering him a seven-year contract as director and actor. Preminger requested producing rights as well, and the deal was sealed. He completed filming on November 5, on schedule and only slightly over budget. ==Critical reception==
