10. Olive Thomas
Having starred in the 1920 film that coined the phrase, Thomas was the original flapper. Her life was glamorous and included a stint as a Ziegfeld Follies showgirl and a marriage to Jack Pickford, brother of the movie star Mary Pickford. Her death came too soon, at the age of 25, when Thomas drank down the mercury dichloride that was intended to treat her husband’s syphilis topically. Whether this was accidental or intentionally suicidal was a matter of debate. But since then, Olive has been said to haunt the New Amsterdam Theatre in New York City, where she once owned the spotlight. Thomas struts around in a green beaded costume that she wore as part of the Follies while clutching a blue bottle. She supposedly appears before men and flirts before she vanishes. She’s been spotted so often by stagehands that a superstition has risen, claiming it’s best to say, “Goodnight, Olive,” as you leave so as not to snub the theatre’s long-time resident.
