In 1909, Polaire was cast in her first silent-film role in "Moines et guerriers". In 1910 she returned to the stage, appearing in London and later in New York. (1910 was the date of her first visit to the U.S. as a celebrity, and publicity releases did not mention her earlier appearances in 1895.) In 1912, back in France, she was offered a role in a film by the up-and-coming young director Maurice Tourneur. She appeared in six of his films in 1912 and 1913. She then returned to the musical stage and began a second tour of the United States, after which she appeared at the London Coliseum. In 1915 Polaire made frequent appearances in London, and involved herself in wartime fund-raising efforts. She returned to films in 1922, but in the declining years of her career had to be content with lesser roles.
