Vera Caspary also wrote the play "Ring Twice for Lora," then later turned it into a novel with a different title, which led to the famous film noir Laura (1944).
The original short story for "Out of the Blue" by Vera Caspary appeared in the September 1947 Today's Woman magazine. The author co-adapted the screenplay. Caspary had written the novel on which Laura (1944), the film noir, was based. The film was so successful Eagle-Lion offered the author a percentage to film her story "Out of the Blue." Like Laura, it involves a "reincarnation" of a woman, but here we are offered a comedy.
Preproduction articles in The Hollywood Reporter announced Joan Leslie and Tom Conway were to star in this picture, and another story noted Eagle-Lion was to borrow James Craig from MGM to be the male lead.
