One of many of Van Johnson's movies where he is in the military. Some have branded him a draft dodger not being in the military during WWII, but after a car crash in 1943 where he sustained such a serious head injury that he had a plate put in his skull he was classified 4-F ("unfit for military service"). He had scars that were covered for movies by heavy makeup but he didn't for Ouragan sur le Caine (1954). Johnson felt that showing scars gave more credence to his naval character.
Franz Waxman composed the score for this film. The theme he used when Jane Wyman's character first enters her New York office was used by George Lucas for his first feature film, THX 1138 (1971). The music was heard in the futuristic shopping mall sequence as elevator music.
After Jane Wyman ("Ruth") and Eileen Heckart ("Grace") pause to talk on a bridge in Central Park, the building on the edge of the park filling half the screen is the Dakota, perhaps New York's most famous apartment building.
Van Johnson had read the Ben Hecht source novella when it had first appeared in the Saturday Evening Post in 1943 and had told his friend Robert Walker that Art Hugenon would be a perfect movie role for Walker, who (like Johnson) was often cast in military roles and would in fact headline L'horloge (1945) which like ''Miracle in the Rain'' focuses on a soldier who finds romance while on leave in New York City. By the time Johnson himself played Hugenon, Walker had been dead for four years. Johnson would recall: "I thought of [Robert Walker] every day when I was working on [the ''Miracle in the Rain''] set."
