Both Audrey Totter and Robert Taylor relished making this film - Totter, because she got to play a professional woman as she did in Lady in the Lake (1946), and Taylor, because he got to act and not just be a "pretty boy".
One day, the filming lasted so late into the night that both Robert Taylor and Audrey Totter missed dinner. Famished, they went to the studio commissary but found it closed. They then tried to go to the restaurants but found them too crowded. Taylor then brought Totter to his home, and his then-wife Barbara Stanwyck made eggs and bacon for them. Totter recalled the event fondly saying, "It was great."
The "unwritten law" mentioned by the lawyer is the assumption that juries would not find a man guilty of murder if he killed his cheating wife.
In this film, Robert Taylor's character's brain damage occurred while a pilot in WWII and in postwar Burma. In real life Taylor flew for many years, both in his own private aircraft and in the military, where he also served as a flight instructor and made training films.
This film has a similar premise to Alfred Hitchcock's Spellbound (1945): a doctor falls in love with a man accused of murder and attempts to treat him in an effort to jog his memory about what really happened and who the real murderer is.
