Instead, the studio rushed her in the romantic comedy Ladies in Love (1936), which was filmed in mid-1936. She shared the female lead with Janet Gaynor, Loretta Young and Constance Bennett, some of whom objected to the large number of scenes that Simon was getting. It was a heavyweight lineup in which Simon's role left her little chance to compete effectively. Trying to avoid quarrels, she hired an assistant to prevent her from making headlines with her behavior. Despite a big build-up, which included a weekly salary even though her first American film was released more than a year after her arrival in the country, Simon's films for 20th Century Fox were only moderately successful. Among others, she was cast in the Janet Gaynor role in the 1937 remake of the silent classic Seventh Heaven (1927), which co-starred James Stewart and flopped. Afterwards, she was cast in Danger – Love at Work (1937), but due to her heavy French accent she had to be replaced by Ann Sothern. Failing in finding her appropriate roles, the studio allowed her to go on an eight-week vacation to France, and following her return in June 1937, she was assigned to Suez (1938), but the project was shelved and she was eventually replaced.
