Lauren Bacall turned down the role as Ruth Wilson because it called for her to appear in a bathing suit. She said: "I'm not a bathing beauty... I'll be embarrassed."
Dale Robertson and Jeff Richards, in early uncredited roles as a hunky pair of lifeguards, appear bare-chested, with dialogue, in minimal (1948) bathing attire in their only scenes. Ronald Reagan, although appearing bare-chested in much of the publicity, is only seen unclothed in the imaginary vision of Virginia Mayo at the end of the trial sequence; Eddie Bracken also appears bare-chested in the publicity, but never in the actual film.
Jones Beach is situated on the south shore of Long Island.
Filmed in mid-1948, and bearing a 1948 copyright statement on the opening credits, but not released until one year later, in mid-1949.
