The 16 Oct 1920 Camera announced the start of principal photography that day at Goldwyn Studios in Culver City, CA. The production was known at the time by its working title, Mr. & Mrs. Miserable Jones. The 20 Nov 1920 Moving Picture World revealed that the first day of shooting took place on Catalina Island, off the coast of Southern California. Among the cast were “fifty bathing girls.” Later that month, the 27 Nov 1920 Camera reported screenwriter Rupert Hughes’s visit to the studio, where he viewed rushes with director E. Mason Hopper. That same issue also stated that the company had returned to Catalina for more location shots. Child actor Newton Hall was included in the cast, as was Baby Virginia Stearns, identified as “Virginia ‘Cuddles’ Stearns,” who was credited with the role of “Harley Jones, Jr.” in the 8 Oct 1921 Camera. An item in the Mar 1921 Picture-Play noted that an unidentified ten-day-old infant also appeared in the film. As stated in the 22 Jan 1921 Motion Picture News, Charles Green, who played “the over-servant,” had previously been a butler for the British Royal family.
       The 18 Dec 1920 Camera announced the official title as Dangerous Curve Ahead. A news item in the 2 Jul 1921 Motion Picture News erroneously referred to the film as Danger Ahead, possibly confusing it with another upcoming release of the same name (1921, see entry). The 1 Jan 1921 Motion Picture News noted that Hopper endeavored to recruit everyone on set for the American Red Cross. The completion of principal photography was reported in the 25 Dec 1920 Camera. Rupert Hughes assisted in editing the film, as stated in the 29 Jan 1921 Motion Picture News.
       The 25 Jun 1921 Wid’s Daily and 23 Jul 1921 Motion Picture News reported that Dangerous Curve Ahead was scheduled to open 2 Oct 1921 in 150 theaters, located in and around major U.S. cities. According to the 2 Jul 1921 Motion Picture News, Goldwyn had recently instituted an advertising policy designed to reach approximately forty-two million people, or forty percent of the U.S. population. Advertisements for the picture were expected to appear in thirty nationally distributed magazines. An article in the 6 Aug 1921 Motion Picture News noted that Goldwyn was offering publicity items to exhibitors, such as four-foot-tall “traffic stanchions” bearing a circular red card, which read, “See Dangerous Curve Ahead.”
       The film opened on schedule, with simultaneous debuts at the California Theatre in Los Angeles, CA, and at the Capitol Theatre in New York City. Although it garnered positive notices from the majority of trade publications, the film received a rather sarcastic review from the Oct 1921 Picture-Play, which described it as “annoying,” particularly in regard to Rupert Hughes’s approach to drama.
