When the counterman asks Mary if she wants two sugars in her coffee and then proceeds to put only two pinches in her cup, this is a reference to war-time sugar rationing that contemporary audiences would have found amusing.
Generally considered the film that caused Olivia de Havilland to sue Warner Brothers over contract rights. She won the lawsuit, resulting in California Labor Code Section 2855, informally known as the "De Havilland Law".
Filmed in the summer of 1942, the picture was not released until over a year later. This picture was tangled up in Olivia de Havilland's famous legal battle with Warner Bros. at the time.
At the end of the film, it is hinted that a guard who was standing outside the White House room where Eddie and Maria were married was in fact the president, Franklin Roosevelt. In reality, FDR was unable to stand under his own power because of the devastating effects of his polio. However, all during his presidency his family and aides hid his incapacity through a variety of means, such as having him walk arm-in-arm beside one of his sons. The effort was so successful that many people swore that they actually saw him walk on his own, in public and in private. The film's ending helped to reinforce this illusion in the mind of the public.
This film won the Best Writing, Original Screenplay Oscar for its only Academy Award nomination.
