As her celebrity grew, after her success in San Francisco, O'Neil embarked on an around-the-world tour, performing in Hawaii, Australia, Egypt, and in many other locations overseas. Those extensive travels and stage appearances were managed by McKee Rankin—an actor, manager, and producer—who was instrumental in also making her a star in Australia and in overseeing her London debut at the Adelphi Theatre on September 1, 1902 in the play "Magda". The next day, back in the United States, "The New York Times" reported on that important performance in England, noting that in the early acts of the play O'Neil "gave an intense, imperious and unequal rendering of the part." The newspaper, however, then added that the actress's "nervousness" later eased on stage and she "aroused the big audience to enthusiasm in the climax of the third act, and obtained a good reception." Unfortunately, two other plays in which O'Neil also starred in London that same month—"Camille" and "Elizabeth, Queen of England"—were poorly received by English critics and forced her to terminate early her plans for additional engagements there in October 1902. "The London Times" wholly dismissed her company's presentation of "Camille" as "flauntingly, overwhelming provincial" and criticised her performance in "Elizabeth, Queen of England" as "lacking tenderness".
